+USB pass-through fails with USBDEVFS_DISCONNECT: Invalid argument
+
+Host Gentoo linux 32bit
+Guest Windows XP SP3
+qemu 1.4.2 and

+The device I am trying to use with the guest is an interface for the Suunto Ambit 2 GPS watch which has no linux support.
+
+When the USB device is plugged in qemu reports to the command line:

+[237757.143585] usb 2-1.5: usbfs: process 12684 (qemu-system-i38) did not claim interface 1 before use
+
+In the windows guest Device Manager a HID device is listed but nothing else happens, no found new hardware dialog or the Suunto software (which is sitting there waiting) is not triggered as it should be.
+
+I have tried successfully with several other devices (flash drive, mouse, printer and video capture device). Because this device pretends to be an HID device my kernel's hid-generic driver was picking it up first until I modified hid-core.c to ignore this vendorid/productid. But still no joy.
+
+I'm guessing it has something to do with the the dmesg lines:
+
+[237755.582778] usb 2-1.5: config 1 has an invalid interface number: 1 but max is 0
+[237755.582781] usb 2-1.5: config 1 has no interface number 0
+
+But read that these warnings are not important though I don't get them for other devices. Nor do I get:
+
+[237757.143585] usb 2-1.5: usbfs: process 12684 (qemu-system-i38) did not claim interface 1 before use
+
+I've done alot of searching and I've run out of ideas. Any help would be great.
