I am not sure if this is the correct forum, but if not please direct me to the right place.
I am running Red Hat V6.2 as a desktop host OS with Windows 7 as a virtual guest. Everything works fine except a host USB 160 GB hard drive is not operational in Windows 7. The Windows 7 error message in Device Manager is "The device can not start (code 10)". I know that the USB drive is OK because I can plug it in to Windows 7 running natively and it is operational. Also, Red Hat V6.2 has no problem with the USB drive. Note: I have tried multiple different USB drives - all with the same result.
I also have a WXP virtual guest running under this configuration. WXP has the USB drive operational with no issues. Note that virtual guests WXP and Windows 7 do not run simultaneously - only one is operational at any one time. The other is shutdown.
System information:
Box: HP dc6000 with Core2Duo CPU
Memory: 3.8 GB
Host OS: Red Hat Enterprise Linux Client
Version: 6.2 (Santiago)
Kernel: 2.6.32-220.17.1.el6.x86_64
qemu-kvm: 0.12.1.2
libvirtd: 0.9.4
Guest OS: Windows 7 Professional
Version: 6.1.7601 Service Pack 1 Build 7601
Memory: 1.9 GB
I have tried updating the Windows 7 USB driver (USBSTOR.SYS) - same result I have tried uninstalling the driver, then letting Windows 7 reinstall it on a reboot - same result. I have tried reformatting the USB drive with Windows 7 natively installed - same result on the virtual guest.
I have searched the Red Hat knowledge base and prior support cases without finding anything remotely close to this issue. Note: I have Red Hat Self Support so I can not file a support case with Red Hat. Upgrading to Red Hat support is too expensive.
As you can tell, this has been going on for over a month.
Any help or guidance is appreciated.
Thanks.
