Ticket #8544 (closed defect: duplicate)
USB broken in multi-cpu Windows guests on Mac OS X hosts
|Reported by:||omascia||Owned by:|
|Host type:||Mac OS X|
Any Windows 7 guests, 32 or 64 bits, on VirtualBox 4.0.0, 4.0.2, 4.0.4 (never used versions 3.x) running on Mac OS X 10.6 host (never used VB on other Mac OS X versions) fails mounting most of my USB devices (USB flash drives) when the guest has more than 1 cpu configured. Shutdown, bring cpu count to 1, boot, and it looks it succeeds all the times (that I tested). This is of course an unpractical work-around.
With one device, it even fails with 1 cpu (the device works fine with non virtualized Windows and with vmWare and parallels (previous experience on our production test machines). That device is a portable barcode scanner from Symbol (now Motorola), model MC3000. That device very strangely is reported by VirtualBox with a name in "Symbö" (note the strange unexpected and wrong accented character 'ö' instead of the pair of ascii characters "ol" at the end of the name. Due to that name string error, even the single CPU VMs can't correctly mount the device.
Extension Pack (PUEL) is, of course, installed. Should it be tried without?
Should it be tried without the guest extensions installed?
