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?

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,
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!

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.

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."

That's sounds plausible. Configuration 0 contains no interfaces and thus consumes no bandwidth.

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

First of all, according to the log, your program transfers data to and from bulk endpoints, not to or from isochronous endpoints. Second, it's irrelevant how much data you *want* to transfer. In order to transfer data you first have to configure the device.

So, for what I understood, I only have two options: 1 - Get another EHCI Host controller, so I can split the devices. 2 - Fix the firmware, so that the default interface setting has non isochrounous endpoints. Is that correct? If so, do you know any tool to edit the firmware? The hardware I'm using was not made by me, so I'll something to change ther firmware. Thanks Stephan, and Cheers!

You need the firmware's source code to fix it, unless you want to spend endless hours reverse engineering hex files. Apart from that, by fixing the firmware on your own you will void the manufacturer's warranty. But, what about a third option?: Contact the manufacturer, tell them about the broken firmware and ask for a software update. If they won't do this, then send the device back and request a refund.

Hello,
Stephan, thank you for all the information. I'll try to contact the
manufacturer as you suggested, but this will certainly take a lot of time.
Meanwhile, I'll try to workaround.
But I question raised in my mind: these devices have four endpoints. Two
isochronous (0x01) and two bulk (0x02), isn't that right? The endpoints I'm
using are isochronous and they work fine until I have the bandwidth issue.
But whenever I try to use the other two endpoints, the application just
freezes. There's no error message, no nothing. The program stops and I can't
even close it using Window's task manager. Do you have any idea why that
happens? If I could use the bulk endpoints, at least the bandwidth wouldn't
be a problem anymore, right?
here goes the testlib's log again:

Hi there,
I made some tests using all the endpoints to see what messages I would get
from Debug View logs. Here are the results:
I can only write using endpoint 0x04. If I use endpoint 0x02, the
application freezes. If I use endpoints 0x86 or 0x88, I get invalid endpoint
error (error: _usb_setup_async: invalid endpoint 0x86-0x88).
Writing with endpoint 0x04, I made tests to see where I could read from.
Endpoint 0x88 works fine, but then I get the bandwidth problem. Using
endpoint 0x02, I get the invalid endpoint error (error: _usb_setup_async:
invalid endpoint 0x02). When I try the endpoint 0x86, I get the worst
result: application freezes and I can't even close it using Windows task
manager.
Debug View logs and the application error messages are shown below. Hope
this helps.

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
