I believe HDD's Device > Monitoring Studio installed a filter driver. > Well it wouldn't be the first time that Microsoft documentation was a bit light on the truth! Your experience suggests that the maximum transfer size field is doing something (contrary to the MS online docs). Slightly off topic, there's also a MS app note stating that for a USB mass storage device to have an executable autorun on it, then it must have the removable bit clear in the response to the SCSI INQUIRY command. Well I've been looking at a U3 flash stick here on the analyzer, and it has that bit set! It has 2 luns, the main one for writing to, and a subsidiary one which appears as a CDROM drive (it fills the first byte of the SCSI INQUIRY command with a 5), and off which loads some application software which runs automatically. As for your set configuration problem, have you turned on debugging in the driver and seen why the set configuration failed? I've never used libusb in filter mode. Dan. |

The application should choose which configuration to set (and be aware of what to do if there isn't enough power). Also if the device has multiple interfaces, then you really don't want libusb to be setting the configuration since it should already be set. Linux does set the configuration automatically... I don't understand why you are worried about the maximum transfer size setting, from MS website: http://msdn2.microsoft.com/en-us/library/ms790478.aspx In Windows 2000 *USBD_CreateConfigurationRequestEx* <http://msdn2.microsoft.com/en-us/library/ms790505.aspx> initializes *Pipes[i].MaximumTransferSize* to the default maximum transfer size for a single URB read/write request. The client driver can specify a different maximum transfer size in the *Pipes[i].MaximumTransferSize*. The USB stack ignores this value in Windows XP, Windows Server 2003 and later operating system. So according to that it shouldn't make any difference what it's set to on XP. More assertively: http://msdn2.microsoft.com/en-us/library/ms790486.aspx Windows XP, Windows Server 2003 and Later Operating Systems In Windows XP, Windows Server 2003 and later operating system, the *MaximumTransferSize* member of the USBD_PIPE_INFORMATION <http://msdn2.microsoft.com/en-us/library/ms793357.aspx> structure is obsolete. The USB stack ignores the value in *MaximumTransferSize* for both composite and non-composite devices. To regulate the bandwidth used by their devices, client drivers must either change the Alt settings for an interface or restrict the maximum packet size by setting *MaximumPacketSize* to some value less than or equal to the value of of /wMaxPacketSize /defined in device firmware for the current Alt settings. .

The backend is fully coded but has not been tested very much and I don't know if real data transfers actually work. What's still missing are more unit-tests (see tests/src folder) and a test firmware that's 100% compliant with the HID spec (see tests/firmware folder). It would be really nice if someone with good HID expertise would contribute to this backend. > PICkit 2 does have two configurations, now it only display the first. Is this > normal? Yes that's normal. The descriptors you see when using Windows' HID driver are not read from the device (Windows doesn't provide any API for this). These descriptors are instead generated by the HID backend based on the information provided by Windows' HID API. Have a look at the source code and see how it works. The backend assumes that every HID device has only one configuration, one interface, and 1-2 interrupt endpoints. >=20 > And if I want to try out a libusb based program ported from Linux, how do I > use the HID backend (without using the device driver)?

Dan: Yes, I see your point. There are a couple of other filter drivers installed on my Windows XP SP2 PC. Could they possibly be causing problems for set_configuration()? I was trying to call set_configuration() originally from my driver and it had no effect. I saw that it was commented out in pnp.c, so I commented it back in, rebuilt the libusb0.sys driver, installed it, rebooted my PC and saw that none of my USB devices were working. When I set "MaximumTransferSize" to 65535 in pnp.c and repeated these steps my USB devices again functioned after the reboot. ??? I believe HDD's Device Monitoring Studio installed a filter driver. Stephan: I was able to get the latest source via SVN. Thanks for adding the composite device support!!!

The application should choose which configuration to set (and be aware of what to do if there isn't enough power). Also if the device has multiple interfaces, then you really don't want libusb to be setting the configuration since it should already be set. Linux does set the configuration automatically... I don't understand why you are worried about the maximum transfer size setting, from MS website: http://msdn2.microsoft.com/en-us/library/ms790478.aspx In Windows 2000 *USBD_CreateConfigurationRequestEx* <http://msdn2.microsoft.com/en-us/library/ms790505.aspx> initializes *Pipes[i].MaximumTransferSize* to the default maximum transfer size for a single URB read/write request. The client driver can specify a different maximum transfer size in the *Pipes[i].MaximumTransferSize*. The USB stack ignores this value in Windows XP, Windows Server 2003 and later operating system. So according to that it shouldn't make any difference what it's set to on XP. More assertively: http://msdn2.microsoft.com/en-us/library/ms790486.aspx Windows XP, Windows Server 2003 and Later Operating Systems In Windows XP, Windows Server 2003 and later operating system, the *MaximumTransferSize* member of the USBD_PIPE_INFORMATION <http://msdn2.microsoft.com/en-us/library/ms793357.aspx> structure is obsolete. The USB stack ignores the value in *MaximumTransferSize* for both composite and non-composite devices. To regulate the bandwidth used by their devices, client drivers must either change the Alt settings for an interface or restrict the maximum packet size by setting *MaximumPacketSize* to some value less than or equal to the value of of /wMaxPacketSize /defined in device firmware for the current Alt settings. .

Yes that's normal. The descriptors you see when using Windows' HID driver are not read from the device (Windows doesn't provide any API for this).

The application should choose which configuration to set (and be aware of what to do if there isn't enough power). Also if the device has multiple interfaces, then you really don't want libusb to be setting the configuration since it should already be set. Linux does set the configuration automatically... I don't understand why you are worried about the maximum transfer size setting, from MS website: http://msdn2.microsoft.com/en-us/library/ms790478.aspx In Windows 2000 *USBD_CreateConfigurationRequestEx* <http://msdn2.microsoft.com/en-us/library/ms790505.aspx> initializes *Pipes[i].MaximumTransferSize* to the default maximum transfer size for a single URB read/write request. The client driver can specify a different maximum transfer size in the *Pipes[i].MaximumTransferSize*. The USB stack ignores this value in Windows XP, Windows Server 2003 and later operating system. So according to that it shouldn't make any difference what it's set to on XP. More assertively: http://msdn2.microsoft.com/en-us/library/ms790486.aspx Windows XP, Windows Server 2003 and Later Operating Systems In Windows XP, Windows Server 2003 and later operating system, the *MaximumTransferSize* member of the USBD_PIPE_INFORMATION <http://msdn2.microsoft.com/en-us/library/ms793357.aspx> structure is obsolete. The USB stack ignores the value in *MaximumTransferSize* for both composite and non-composite devices. To regulate the bandwidth used by their devices, client drivers must either change the Alt settings for an interface or restrict the maximum packet size by setting *MaximumPacketSize* to some value less than or equal to the value of of /wMaxPacketSize /defined in device firmware for the current Alt settings. .

Can I assume that the HID backend is kind of working now? >=20 It's only working partially. The backend is fully coded but has not been tested very much and I don't know if real data transfers actually work. What's still missing are more unit-tests (see tests/src folder) and a test firmware that's 100% compliant with the HID spec (see tests/firmware folder). It would be really nice if someone with good HID expertise would contribute to this backend. > PICkit 2 does have two configurations, now it only display the first. Is this > normal? Yes that's normal. The descriptors you see when using Windows' HID driver are not read from the device (Windows doesn't provide any API for this). These descriptors are instead generated by the HID backend based on the information provided by Windows' HID API. Have a look at the source code and see how it works. The backend assumes that every HID device has only one configuration, one interface, and 1-2 interrupt endpoints. >=20 > And if I want to try out a libusb based program ported from Linux, how do I > use the HID backend (without using the device driver)?

The results of specifying a transfer that is larger than 64 KB on a non-control endpoint are undefined." http://aech.net/Driver/USB%E7%A8%8B%E5%BA%8F%E7%9A%84%E5%8A%A0%E8%BD%BD. doc=20 http://support.microsoft.com/kb/832430=20 http://support.microsoft.com/kb/200977/=20 You had select_configuration() commented out in pnp.c and if I uncommented it as it was previously coded with 65536 as the maximum transfer size, then none of my USB devices would function.

Yes that's normal. The descriptors you see when using Windows' HID driver are not read from the device (Windows doesn't provide any API for this).

Why do you think that a max transfer size of 65536 (0x10000) is wrong? This number must be an integer multiple of common endpoint buffer sizes (8, 64, 512, 1024). If it would be 0x10000 - 1 then transfers >= 0x10000 bytes won't work any more. Stephan > > > I fixed set_configuration() which I found to be broken.

I built the new version with MinGW and it seems to run fine. I have two HID device attached, a PICkit 2 USB programmer from Microchip and a Microsoft Baisc Optical Mouse. Using the default system HID driver, I can still run the test program. Can I assume that the HID backend is kind of working now? PICkit 2 does have two configurations, now it only display the first.

The current version (0.1.12.1) works without any problems on vista-32bit but NOT on vista-64bit. Furture versions of the DLL will use vista's built-in winusb.sys driver and will therefore work on both platforms.

Yes, there is a problem AFAIUI. The best that can be done at
present is for the read thread to transfer its data to the
FIFO and immediately begin the next read. The problem is that
the gap is of course non-zero, so it appears possible for data
to be lost during that time.
It's not a system that you'd stake your life on :-(
We have a small USB device embedded in one of our products.
This device can be reprogrammed in-application. My worst
nightmare is that data loss will occur out in the field
during reprogramming and turn the machine into a brick.
It will be expensive to recover.

I don't know. However, I'd suggest that it would be useful
to have a FIFO built in to libusb at low level so that data
loss can't happen. I don't mind whether the calling programme
mallocs the space and passes it to libusb, or the calling
programme requests libusb to reserve it itself.
Unless someone has a neater way to avoid data loss?
Dave

Hi Dave ! Thanks for your answer. I don't really see how the length of the timeout makes any difference. The application in question does already run in a separate thread and a FIFO is used for the data received. The timing gap I'm trying to close with the ping-pong solution is from the point where usb_bulk_read() returns with data to the point in time where usb_bulk_read() is entered again. I have also noticed that libusb (or is it windows usb subsystem ?) actually buffers data, but I have no idea of the size of the buffers...

Not strictly an answer to your question, but I have used the Linux version of libusb with interrupt transfers, in other respects like you show above. Yes, I lost packets occasionally. I had to buy a USB analyser to show where the problem occurred. You need to set the timeout high enough that it will only ever be invoked in the case of a genuine failure. If this gives you a problem of responsiveness in your programme, i.e. you really need asynchronous transfers, then yes, it's a problem. I solved it by using pthreads and a FIFO. I'm pleased to report that pthreads seems to work OK under win32 too.
