Problems with proxying audio-video devices
Hello. I'm trying to use usb-proxy with webcams and an external sound card.
My Microsoft webcam is successfully proxying, but requesting an image ends with the error: ioctl(USB_RAW_IOCTL_EP_ENABLE): Invalid argument.

The external sound card has the same problems as the Logitech camera.
I know that raw-gadget and usb-proxy didn't support isochronous transfers before. But it should probably work now.
Unfortunately, the issues described on this page didn't help me.
Try turning on debugging output for Raw Gadget and see if you get any error messages in the kernel log. And you can also add extra debugging print calls into raw_ioctl_ep_enable to see why it is failing.
My guess is that your UDC does not support emulating endpoints with required parameters (maybe does not support isochronous endpoints at all?) and thus usb_gadget_ep_match_desc fails to find a match. So you can try using a different board.
Thanks for your reply.
I switched to raw-gadget-dev, but it didn't help.
I rebuilt the project with #DEBUG, but I don't see any effect: "dmesg | grep gadget" returns:
[ 5.862684] systemd[1]: Reached target usb-gadget.target - Hardware activated USB gadget. [ 47.021589] raw_gadget: loading out-of-tree module taints kernel. [ 47.021802] raw_gadget: module verification failed: signature and/or required key missing - tainting kernel
The datasheet for my processor says:
One USB 2.0 OTG(USB0), with integrated USB 2.0 analog PHY - Compatible with USB2.0 Specification - - - - - - Supports High-Speed (HS, 480 Mbit/s), Full-Speed (FS, 12 Mbit/s) and Low-Speed (LS, 1.5 Mbit/s) in host mode Supports High-Speed (HS, 480 Mbit/s), Full-Speed (FS, 12 Mbit/s) in device mode Compatible with Enhanced Host Controller Interface (EHCI) Specification, Version 1.0, and the Open Host Controller Interface (OHCI) Specification, Version 1.0a for host mode Up Up to 8 User-Configurable Endpoints (EPs) for Bulk, Isochronous, and Interrupt bi-directional transfers Supports (4KB+64Bytes) FIFO for all EPs (including EP0) Supports point-to-point and point-to-multipoint transfers in both host and peripheral modes
Most likely, my UDC supports isochronous endpoints. Or is this irrelevant?
So, I'm still struggling with the problem.
If you don't see any new messages in dmesg, that's likely because your distro disabled showing debug messages. Try adjusting /proc/sys/kernel/printk.
I managed to get these messages from dmesg:
[ 109.209930] raw_gadget: loading out-of-tree module taints kernel. [ 109.216291] raw_gadget: module verification failed: signature and/or required key missing - tainting kernel [ 110.468397] usb 1-1: reset high-speed USB device number 2 using ehci-platform [ 111.020431] usb 1-1: reset high-speed USB device number 2 using ehci-platform [ 111.400498] raw-gadget.0 gadget.0: gadget connected [ 112.184372] raw-gadget.0 gadget.0: fail, bad endpoint descriptor [ 112.193929] raw-gadget.0 gadget.0: gadget disconnected
The endpoint number is also known: 0x87
Ah, I suspect this is related to #12.
Please run the proxy with verbose log enabled (so that print_eps_info prints its stuff) and show the log.
And also share the USB descriptors of the device you're trying to emulate (run lsusb -v and find the device).

Here's the output from usb-proxy with --verbose. I hope I did it right.

Yeah, looks like the same issue: the device uses endpoint addresses 6 and 7 (0x86 and 0x87), but your UDC only supports addresses up to 4.
You can try modifying setup_host_usb_desc in usb-proxy.cpp to set temp_endpoint.bEndpointAddress to 0x82 whenever it is 0x86 and also do same for 0x83 <= 0x87. Or maybe bEndpointAddress needs to be patched just before the call to usb_raw_ep_enable.
Try both approaches separately, perhaps one of them will work.
Both approaches produce errors:
libusb: error [submit_bulk_transfer] submiturb failed, errno=2 Transfer error receiving on EP83: Input/Output Error ioctl(USB_RAW_IOCTL_EP0_WRITE): Invalid argument
I probably need to change the endpoint addresses in several places.
Well, now a have this. I added this temporary fix to proxy.cpp before calling usb_raw_ep_enable():
struct usb_endpoint_descriptor temp_usb_ep_desc = ep->thread_info.endpoint;
if((temp_usb_ep_desc.bEndpointAddress & 0b00000111) > 0x04){
temp_usb_ep_desc.bEndpointAddress -= 4;
}
After this, function is called with the temporary descriptor:
ep->thread_info.ep_num = usb_raw_ep_enable(fd, &temp_usb_ep_desc);
The webcam doesn't disconnect immediately, but it still disconnects when i try to capture an image:
ioctl(USB_RAW_IOCTL_EP_ENABLE): Invalid argument
To fix this, I limited the endpoint packet size to 512 bytes (the maximum for my UDC) in usb-proxy.cpp:
if(temp_endpoint.wMaxPacketSize > 512){
temp_endpoint.wMaxPacketSize = 512;
}
This solved the webcam disconnection issue. But I still can't capture an image: the screen is blank at any resolution.
And do you see any data flowing through the endpoints (the proxy should print it if you run it with debugging output enabled). If you do, then maybe the data rate is just not good enough to produce an image.
But at this point, I don't have specific ideas on how to fix this. You can try sniffing USB on the host / tracing the host driver to see where things go wrong. Or try using a different UDC and see if that works.
Thank you for you help!
I see data in the console, but it seems to be less than there should be. For example:
