USB devices in guest don't attach when EHCI enabled

Reported by: jpl Owned by:

Version: VirtualBox 3.2.0 Keywords:
Cc: Guest type: Linux
Host type: Linux


I'm using Debian as host, experimenting with Debian and Finnix (a Debian-based LiveCD) as guests. I'm unable to attach an external storage USB 2.0 device in guest if the EHCI controller is enabled (I tried with a flash disk and external HD). It works ok with the EHCI controller disabled. I'm observing dmesg in guest, with the following symptoms:

  1. The device appears to be recognized (e.g. id, serial number appear correctly)
  2. After that I get a series of "reset high speed USB device using ehci_hcd" messages with a few seconds delay between them.
  3. Finally a message "Device offlined - not ready after error recovery" appears.

When I detach and re-attach the device, the sequence of messages is repeated.
