/dev/ttyACM0 does not work with gentoo-sources-2.6.31. A patch can be found under http://www.spinics.net/lists/linux-usb/msg22102.html . It would be very nice if this patch could make it into 2.6.31-r1. Reproducible: Always Steps to Reproduce: 1.See link. 2. 3. Actual Results: UTMS-Card device cannot be opened with kernel-2.6.31
I can confirm that the patch from the link works on a thinkpad t400. Regards, Phillip
