In /sys/dev/usb/usb_device.c :
There is some code to re-enumerate the device, when errors are detected. Maybe
we should add an automatic re-enumeration in case the full device descriptor
cannot be retrieved aswell.
Search for:
err = usbd_req_get_desc(udev, NULL, NULL, &udev->ddesc,
USB_MAX_IPACKET, USB_MAX_IPACKET, 0, UDESC_DEVICE, 0, 0);
if (err) {
DPRINTFN(0, "getting device descriptor "
"at addr %d failed, %s!\n", udev->address,
usbd_errstr(err));
/* XXX try to re-enumerate the device */
err = usbd_req_re_enumerate(udev, NULL);
if (err) {
goto done;
}
}
Some lines down you patch the code like this:
/* get the full device descriptor */
err = usbd_req_get_device_desc(udev, NULL, &udev->ddesc);
if (err) {
DPRINTF("addr=%d, getting full desc failed\n",
udev->address);
+ /* XXX try to re-enumerate the device */
+ err = usbd_req_re_enumerate(udev, NULL);
+ if (err) {
+ goto done;
+ }
- goto done;
}
