USB Audio interface Tascam US122l crashes Client System => Fixed in SVN

[machete]

Hi, I have a tascam us-122l audiointerface which i would like to use with a windows xp virtual machine. As soon as I enable the interace for use in the VM, the VM crashes. When I use a USB filter for, it crashes as soon as windows tries to load the USB drivers. Same thing happens on Windows 7 (both systems are 32bit)

found something: dmesg shows:

[ 7460.402501] VirtualBox[31044]: segfault at 0 ip 00007fbed6cf997e sp 00007fbeb5d2c8f8 error 4 in libc-2.13.so[7fbed6c6f000+18a000] [ 7695.859968] VirtualBox[31152]: segfault at 0 ip 00007f3bbb53f97e sp 00007f3b9a59c8f8 error 4 in libc-2.13.so[7f3bbb4b5000+18a000]

libc-2.13.so is part of the lib32 library so maybe this isn't a virtualbox problem? unfortunately i am running a x86-64 system so I can't test it on a x86 sys

[Frank Mehnert]

No, it is quite sure this is a VirtualBox problem because the libc function probably crashes as a result of invalid parameters. Can you provide a ​core dump? If so, please send me a private mail at frank _dot_ mehnert _at_ oracle _dot_ com.

[machete]

Sure! thanks a lot for looking into this :)

unfortunately your mailserver gives me the following: Diagnostic-Code: X-Postfix; message size 16919712 exceeds size limit 14680064

of server acsinet11.oracle.com[141.146.126.233]

also I am unable to upload it here (file extends the 4MB limit) so I uploaded it to my server..i hope that's okay

The bug appears both with OSE and with PUEL, I made the dump with OSE, if you want me to make it with PUEL just tell me

cheers

[Frank Mehnert]

Yes, please send me a core dump for the package from the official website because I cannot work with core dumps for OSE binaries.

[Frank Mehnert]

Thanks for the core dump. We believe we found the problem.

[Frank Mehnert]

Could you check if ​this package fixes your issue?

[machete]

Yes, it works! Only thing I could complain about is that the VM lags as soon as I enable the audio interface (hangs every 2 seconds for about 0.5 second). ps: I installed the drivers for the audio interface!

seems to be an issue with the driver, absolutely no lags after i removed it.

USB 2.0 was disabled, works like a charm now! thank you guys :)

Thanks for the report and the feedback!
