OHCI Host Controler Died

OHCI Host Controler Died

[Remo Inverardi]

I'm running Debian SID with a custom Linux 2.6.0-test5 kernel on my
Compaq Evo N800v notebook. When running Windows XP in VMware, and
accessing an Aladdin eToken (cryptographic USB smartcard) from my
virtual machine, the USB host controller crashes immediately.

Here's the interesting part of lspci:

Here's my kernel config:

Here's the interesting part of syslog:

By the way, if I insert the token when VMware is *not* running,
/proc/bus/usb shows that the token was detected correctly:

Any ideas?

Thanks for your time, Remo

Great, go bug vmware then :)

I didn't think their product was supposed to be working on 2.6 yet
anyway...

Greg,

> Great, go bug vmware then :)

I will -- but ...

I was under the impression that all of VMware's USB code is running in 
user space. Running "grep -ir usb ." in VMware's modules/source 
directory did not return any hits, so this assumption is probably correct.

This does look like a kernel bug to me, since it should not be possible 
to crash the OHCI driver from user space.

Regards, Remo

I'm under that impression too, but due to them requiring kernel drivers
to support their program, I can not be sure.

I agree.  And if you can figure out how it does that, we would really
appreciate it :)
