[Qemu-devel] [Bug 1440843] Re: Guest WinXP crashes when trying to use a USB spectrometer

[Erik Rull]

Which version is used? Try the latest QEMU or at least QEMU 2.0.
The behavior sounds like a pretty old QEMU version.
Additionally, enable the EHCI controller (see example in the docs subdirectory).
It it working on a native Windows XP?

Title:
  Guest WinXP crashes when trying to use a USB spectrometer

Status in QEMU:
  New

Bug description:
  I'm using Amadeus spectrometer (OceanOptics USB250) via Windows-based
  software "Quantum". I've tried six ways of attaching it to QEMU:

  1. command line parameter "-device usb-host,hostbus=3,hostaddr=25"
  2. command line parameter "-device usb-host,vendorid=0x2457,productid=0x1030"
  3. command line parameter "-usbdevice host:2457:1030
  4. command line parameter "-usbdevice host:3.25"
  5. qemu console command "usb_add host:2457:1030"
  5. qemu console command "usb_add host:3.25"

  From these, only "-device ..." options work, i.e. numbers 1 and 2 in
  the list above, and all others lead to IRQL_NOT_LESS_OR_EQUAL BSOD in
  usbuhci.sys when I launch Quantum, which tries to start acquiring
  spectra.

  I've also tried to reproduce the crash with a flash drive, but
  couldn't — it seems to work reliably in this case.
