The formal 2.0 USB specifications at http://www.usb.org should tell you why and how a stall happens, and (probably) what error recovery mechanisms are available. Also, it's often worth checking the existsing kernel source to see how other drivers deal with these kinds of issues, try running grep: $ grep ST_STALL /usr/src/linux-2.4.16/drivers/usb/* /usr/src/linux-2.4.16/drivers/usb/usbnet.c: if (urb->status == USB_ST_STALL) { /usr/src/linux-2.4.16/drivers/usb/usb-ohci.h: /* Stall */ USB_ST_STALL, $ grep ST_STALL /usr/src/linux-2.4.16/include/linux/* /usr/src/linux-2.4.16/include/linux/usb.h:#define USB_ST_STALL (-EPIPE) /* pipe stalled, also in urb->status*/ >From the output above it's probably worth reading the source for usbnet.c, might give you an idea.
