The user is encountering an issue where USB pass-through fails in QEMU with the error message "USBDEVFS_DISCONNECT: Invalid argument." They're using Gentoo Linux as the host and a Windows XP SP3 guest, along with QEMU version 1.4.2. + +First, I'll look at the provided information to identify possible causes. The user mentioned that they've successfully used other USB devices like a flash drive, mouse, printer, and video capture device, so the problem seems specific to this particular device—the Suunto Ambit 2 GPS watch. This suggests it's not a general issue with QEMU's USB handling but something related to how this specific device is being handled. + +Looking at the dmesg logs provided: + +- The device is detected as usb 2-1.5, with vendor ID 1493 and product ID 0019. +- There are warnings about invalid interface numbers: config 1 has an invalid interface number (1) but max is 0, and it has no interface number 0. +- Additionally, there's a message stating that the process didn't claim interface 1 before use. + +These log entries point towards issues with how the USB device's configuration is being handled. The kernel is noticing problems with the USB device's descriptors—specifically, the configuration descriptor might be malformed or misrepresented within QEMU. This could be due to incorrect handling of the USB device's data during setup in QEMU's code. + +The error "USBDEVFS_DISCONNECT: Invalid argument" suggests that there's a problem when trying to disconnect the device, possibly because it wasn't properly connected or configured initially. The fact that the user had to modify the hid-core.c driver indicates that the host system was attempting to handle this as an HID device, but even after that change, the issue persists. + +Considering the categories provided: mistranslation, assembly lowering, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor. + +The primary issue seems to be with USB device handling. The USBDEVFS_DISCONNECT error relates to how QEMU interacts with the host's USB subsystem and handles devices passed through to the guest. This falls under the 'device' category because it pertains to the management of hardware devices in the virtualization environment. + +Other categories like kernel or hypervisor could be related, but the specific error is more about device handling rather than the overall system kernel functions or hypervisor operations. The problem arises when trying to pass a USB device through, so 'device' seems the most appropriate category. +</think> + +device \ No newline at end of file |
