Hi, I have a usb network device where part of functionality is implemented in firmware. To communicate with the firmware I need to submit bulk URBs to one of the EPs. Unfortunately when device is being unbound or the driver is removed from the kernel EPs are disabled before .disconnect() is called and I cannot tell the firmware to bring the device down. As a result the device sometimes locks up on rebind.
I suspect this is not an uncommon problem. I tried usb_reset_device() and it seems to help but not with all sorts of hangs. I don't have any documentation of the device - only a half-broken vendor driver which doesn't deal with this case. Is there a way to submit bulk URBs from .disconnect() callback? Are there any best practices on how to deal with such hardware?
