Sorry for not getting back to you sooner. I am off today. I made 3.2.20 work after rerunning "make config" on Friday. With the output of lsusb and dmesg from Nils, looks like either MAXCONTACTS, or device_type, or both are the root cause. MAXCONTACTS is not 2. The problem is that I do not have an X220T (0xE6) system to test with. My testing is on an 0xE3 system, which does not report MAXCONTACTS. So, a patch for upstream is needed. I'll make a patch tomorrow for Nils to test.
