Hello Stephan,
First of all, thank you for being so helpful and so quick! :D
Now let's get back to the problems:
1- I can't spread the devices as I have only one EHCI host controller.
2- I won't be able to use configuration 0, as if there's no interface, I
cannot transfer data, right?
3- Isn't there a way to lower the packetsize?
About the packetsize, the amount of data I can transfer has something
to do with it? Because I usually transfer 2048 bytes, and if I transfer onl=
y
64 bytes I'm still not able to use the third device. And if the maxpacktsiz=
e
is 1024, why can I transfer 2048? Could you point me something to read abou=
t
this?
4- Here goes DebugView log:

You can see I make four transfers with each device: bulk write and read and
interrupt write and read. When I get to the third device, I get this error.
In my program, now I get the following error message:
Opened Device 3.
Configuring Device 3...................LIBUSB_DLL: error:
usb_set_configuration:
could not set config 1: win error: *Um dispositivo conectado ao sistema n=
=D2o
est=DF
funcionando.*
[error: setting config 1 failed]
The message in portuguese says: "a device conected to the system is not
working".
Any thoughts?
Cheers,
Dan

Here are the logs: Add usb=5Fset=5Fdebug(255) after usb=5Finit() to bulk.c.=20 It should print out some debug information then. What errors do you see=3F >=20 > [...] >=20 > And here goes the device's descriptors: >=20 Thanks, that explains why Windows won't configure your four devices: * each device has two isochronous endpoints (bmAttributes =3D=3D 0x01) * each of these endpoints has a wMaxPacketSize value of 1024 and a bInterval value of 1 According to the USB spec (section 9.6.6) your four devices would require the following bandwidth to operate (I assume that your devices are high-sp= eed USB): * interval: bInterval =3D=3D 1 =3D> 2^(bInterval - 1) * 125=B5s =3D> 125=B5s * bandwidth of one endpoint: 1024/125=B5s * 1000 =3D 8Mbytes/s * bandwidth of one device: 8Mbytes/s * 2 =3D 16Mbytes/s * bandwidth of four devices: 64MBytes/s !! One single host controller just can't handle this amount of data. That's why Windows refuses to configure more than two devices. =20 But it should work if you spread your devices across multiple host controllers. Apart from that, your device's firmware is not compliant with the USB specification. Quote from the spec, section 5.6.3: "All device default interface settings must not include any isochronous=20 endpoints with non-zero data payload sizes (specified via wMaxPacketSize=20 in the endpoint descriptor). Alternate interface settings may specify non= -zero=20 data payload sizes for isochronous endpoints. If the isochronous endpoint= s=20 have a large data payload size, it is recommended that additional alternat= e=20 configurations or interface settings be used to specify a range of data pa= yload=20 sizes. This increases the chance that the device can be used successfully= in combination with other USB devices."

Hi there, One more thing to add: when I call the function usb_set_configuration(devH, 1), if I change the 1 to zero, then I pass thru the configuration, but then I don't get to claim the interface (get an error on this function: usb_claim_interface(devH, 0) . I tried changing the number on this function too, but it didn't work. Hope that helped a bit.

Hi,
I used the DebugView, but when I use the bulk program, it only returns two
blank lines. When I use the test program, it returns lots of things. Here
are the logs:
*bulk.c:*
(two blank lines).
*test program:*

I made some tests and got even more confused: if I jump the first and second
devices, testing the third (or fourth) device first, I still get the same
error. So would it be a power or bandwidth problem? I'll think of some more
tests to do and will post here if I find something that could help.
Thanks and cheers!

I installed the 0.1.12.1 driver again, and fired up Snoopypro, hoping to capture the differences between the previous version that worked, and this version. Unfortunately this didn't do any good. It showed that the device keeps getting re-enumerated every second, so Snoopypro just pops up a new trace window each second, empty of any USB transactions. I turned on __usb_debug in the driver, and strangely when I run the application this occasionally gets the device to work (but not every time). I get the following messages when this happens: LIBUSB_DLL: info: usb_os_init: dll version: 0.1.12.1 LIBUSB_DLL: info: usb_os_init: driver version: 0.1.12.1 LIBUSB_DLL: info: usb_os_find_busses: found bus-0 LIBUSB_DLL: info: usb_os_find_devices: found \\.\libusb0-0001--0x04db-0x005b on bus-0 LIBUSB_DLL: error: usb_reap: timeout error After this the device remains available until I reset it or reconnect it.

What kind of error messages does DebugView (http://www.microsoft.com/technet/sysinternals/utilities/debugview.mspx) capture when you try to configure your devices? Also, it would be helpfull if you would post your device's descriptors (output of testlibusb-win.exe).

Hi Stephan,
1- I tried to find the error definitions before posting, and in errno.h I
get this only:
#ifndef __ERROR_H__
#define __ERROR_H__
/* Connection timed out */
#define ETIMEDOUT 116
typedef enum {
USB_ERROR_TYPE_NONE = 0,
USB_ERROR_TYPE_STRING,
USB_ERROR_TYPE_ERRNO,
} usb_error_type_t;
void usb_error(char *format, ...);
void usb_message(char *format, ...);
const char *usb_win_error_to_string(void);
int usb_win_error_to_errno(void);
#endif /* _ERROR_H_ */
2- There's no value named bMaxPower, but there is a MaxPower value, which is
50.
3- The devices are bus-powered.
4- I don't know if the endpoints have these characteristics, but I can
interrupt write and read, so I guess the device has interrupt endpoints.
About being isochronous, I can't really assure it is. It might be, as it is
a 2.0 device.
When I put three of these devices, I get this error, but if I put two
devices and another bus-powered device, such as a pen-drive, it works fine.
But if the problem is really windows refusing to configure the device, is
there a way to make the SO not refuse it?
Thanks for the answers Stephan!
Cheers!
Dan

This could be either a power or bandwidth problem. Windows will refuse to configure the devices of they request too much power or bandwidth. What's the bMaxPower value of your device's config descriptor? Are your four devices connected to a bus-powered or to a self-powered hub? Do your devices have interrupt or isochronous endpoints?

This sounds like a great idea! I'll add a native HID backend to the next version of the DLL.

Hi there, Is there a table of the function's return values? I'm using a test board that has four devices with the same characteristics, such as vendor and product ids, number of and address of endpoints, and all others. But when I try to use more than two of these devices, I get a -5 error from the function usb_set_configuration() on the third device (after accessing, writing and reading from the other two).

You need to manually "upgrade" the HID driver to the libusb device driver. It is quite troublesome and I do not know if it will work for you since your device is more complicated than the PICKit 2 I am using. Here is the procedure for the PICkit 2. For the detail procedure, you may want to look at my Microchip Forum post. http://forum.microchip.com/tm.aspx?m=110205 Regards, Xiaofan |

Okay, how exactly do I do that? install-filter.exe doesn't run at all on my computer, just quits with no output... Should I run the NSIS uninstaller for libusb-win32-filter-bin-0.1.12.1.exeand reboot, would that do it? Am I just supposed to be using the "bin" tar ball by itself?

If not the PC will hang since the Windows HID driver is still there. I have problem with this last time and Stephan's suggestion is working for me. |

There is a libHID library on http://libhid.alioth.debian.org/ that claims it aims to work everywhere (Windows is listed on the website)... in practise the source repo doesn't actually look like it has any code for win32 anywhere in there. I've been spoiled by a Delphi HID component that works wonderfully on Win32 (from the awesome Delphi Jedi's - http://www.delphi-jedi.org/), but that is likely non-portable and also being written in Pascal...

Here's what I tried this evening: - "install-filter.exe -h" in a cmd window. No output, no change in USB devices show in test program. - open install-filter.c, read that -u is to uninstall filter - run "install-filter.exe -u" in a cmd window. No output, no change in USB devices show in test program. - put usb_uninstall_service_np() into first line of bulk.c example and run that, that removes all but mouse device. - go download the "libusb-win32-device-bin-0.1.12.1.tar.gz" which has a whole bunch of shit that is not in the libusb-win32-filter-bin-0.1.12.1.exeinstall that I got before, like inf-wizard that I am supposed to run. - run inf-wizard, pick out my device from the list to create .inf files. Right click "Install" on generated .inf. - test program shows my mouse and my device (so all that got rid of one device from the list I don't care about) - run my app, no luck app detects mouse and my device and freezes - reboot - test program shows -1.-1.-1.-1 for driver version - change first line of bulk.c to usb_install_service_np() - test program shows only mouse, not my device - right click on my .inf file choose install - test program still only shows the mouse, though inf-wizard still sees all 3 devices... - reboot - all 3 devices appear again in test program - run a c program w/ usb_uninstall_service_np() + quit; - run bulk.c: LIBUSB_DLL: info: usb_os_init: dll version: 0.1.12.1 LIBUSB_DLL: info: usb_os_init: driver version: 0.1.12.1 LIBUSB_DLL: info: usb_set_debug: setting debugging level to 255 (on) LIBUSB_DLL: info: usb_os_find_busses: found bus-0 LIBUSB_DLL: info: usb_os_find_devices: found \\.\libusb0-0002--0x15c2-0xffdc on bus-0 LIBUSB_DLL: info: usb_os_find_devices: found \\.\libusb0-0003--0x06f8-0xb100 on bus-0 <app frozen> Maybe it just doesn't work with composite devices that have multiple HIDs or something (the DJ console is 2 HIDs + a 5.1 sound card all in one device)...

The thing is that you need to uninstall the kernel HID driver and use the libusb-win32 device driver for this kind of HID device. This significantly reduces the usability of libusb-win32 for HID device under Windows. Yet many USB device disguise them as HID device just to avoid writing a device driver. Just wondering if it is possible to use an alternative backend (Windows HID apli) and make libusb a wrapper on top of it. I understand then it should perhaps be called libhid-win32 then. By the way, will the new WinUSB based libusb-win32 solve this issue? Regards, Xiaofan |

Just noting that I've had to revert back to the previous version because one device (the Colorimètre HCFR) doesn't work on the new libusb-win32. I'm not sure how to go about diagnosing why this is so. It basically doesn't appear on the system with the new driver. Graeme Gill. |

This is most likely cause by the fact that you have installed libusb's kernel driver as a filter. This doesn't work properly with some HID devices. Uninstall the filter and install the kernel driver as a normal device driver through an .inf file (use inf-wizard.exe to create one). It should work then.

Remove the while loop and read all data at once:
char buf[1200*64];
usb_bulk_read(udevhandle, 0x81, buf, sizeof(buf), 1000);

Using the bulk.c example, if I try with my mouse (MY_VID 0x04b3, MY_PID 0x310b) I can successfully bulk_read. When I set MY_VID/PID to that of my djconsole I get the same process hang as my djconsole port test program --> "usb_set_configuration" freezes the process everytime... :( Here is what SysInternals ProcessExplorer shows for the process stack: ntoskrnl.exe+0x584d ntoskrnl.exe!KeQueryRuntimeThread+0x5e8 ntoskrnl.exe!CcPurgeCacheSection+0x240 USBPORT.SYS+0x20378 USBPORT.SYS+0x13d5c USBPORT.SYS+0x18dfe USBPORT.SYS+0x21e2 ntoskrnl.exe!Kei386EoiHelper+0x237d usbhub.sys+0x4afa usbhub.sys+0x21d8 ntoskrnl.exe!Kei386EoiHelper+0x237d libusb0.sys+0x32ad libusb0.sys+0x1f0a libusb0.sys+0x140f ntoskrnl.exe!Kei386EoiHelper+0x237d ntoskrnl.exe!RtlIntegerToUnicode+0x66 ntoskrnl.exe!RtlRemoveUnicodePrefix+0x10e4 ntoskrnl.exe!ZwSetSystemInformation+0x23 ntdll.dll!KiFastSystemCallRet libusb0.dll!usb_submit_async+0x1d8 libusb0.dll!usb_set_configuration+0x63 Test5.exe!main+0x8f Test5.exe!__tmainCRTStartup+0x1a6 Test5.exe!mainCRTStartup+0xd kernel32.dll!RegisterWaitForInputIdle+0x49 Suggestions?
