Windows 7 and USB driver

[darkfate]

Hello,

there seems to be a compatibility bug in the VBox USB drivers. I tried v. 3.0.6 and 3.0.8 and both end in the same scenario.

I try to assign my webcam (CAM44U) from a Win7 x64 Host into a Win XP x86 guest machine. At first Win7 shows that it cannot install the driver.

After that i shutdown the guest and install the VBox USB driver by myself by updating the driver from the camera.

After i start my virtual machine everything works ok until i start my cam. The host system crashes with a bluescreen. Like attached in the screenshot.

Because of the Restriction of 400kb i cannot upload my Screenshot... its not necessary.

Host Bluescreen shows:

A Problem has been detected and windows has been shut down..... to your computer.

VBOXUSB.SYS

PAGE_FAULT_IN_NONPAGED_AREA

....

Technical information:

* STOP: 0x00000050 (0xFFFFFA8010C00010, 0x000.....00, 0xFFFFF8800655996C0,0x000..... 002)

* VBOXUSB.sys - ADress FFFFF88065996C0 base at FFFFF88006597000, DateStamp 4aa7ec59

Can you give us access to the minidump of that particular crash? Check ​http://support.microsoft.com/kb/315263 for details about minidumps.

Minidump after a Win7 x64 + VBOX 3.0.8 Crash

Hi, i uploaded the file. Sorry it took long because by following the pasted link was not successfull for me to get a minidump.

It seems that Win7 x64 does not create a minidump if the %SystemRoot%\Minidump folder does not exist. I had to create a %SystemRoot%\Minidump by myself...

Located the problem and a fix will be included in 3.0.10. Thanks for the report.

[darkfate]

It is still not fixed. While i am attaching my webcam (CAM44U) i get a win warning that the usb bandwidth is exceeded.. after a while (10-20sec) i get a BSoD

BSoD with 3.0.10

Not easy to see what's wrong. Could you give us the exact brand and model of the web cam? Just don't use it for now in the VM.

CAM44U, ​http://www.gembird.nl/default.aspx?ref=CAM44U&op=products&op2=item&id=3527 It is no problem for me to buy a new cam ... i just wanted to tell that it is still a possibility to get a bsod with certain usb devices.

[darkfate]

What about the "USB Bandwidth exceeded" warning in the windows taskbar?

[Sander van Leeuwen]

There appears to be some problem getting the configuration for this device. Something is seriously broken in our code, so it just has to be fixed.

[darkfate]

Is there anything i can do? Would it help if i upload big dump? I can also send you the cam if you want :)

icstrasher: your comments have been deleted. I don't see what connection they have with this defect. I suggest you go to the forum and ask there first.

The driver installs correct, but when I try to open the cam I get a Bluescreen on my host.

Please open a new ticket with the outstanding problems. USB host support for Windows hosts was rewritten for 4.1 so test 4.1.6 first.
