I am noticing a loss of USB connection if I accidentally / purposely wiggle the cable near the USB type-C device end, using 6.0-current #150.
I have 2 USB-A male to type-C cables, one implements USB 2.1, the other USB 3.1 I get the same problem with both cables. The problem doesn't happen all the time, about 1 in 10 when I try to replicate it, and I haven't had this problem in the past. I get 2 different types of messages when the problem occurs 1. uhub0: port 2 reset failed 2. uhub0: device problem, disabling port X where "disabling port X" can be either port 2 or port 1 - see below I've also attached a dmesg from boot I can compile a kernel with UMASS_DEBUG if further output is needed Edward. # # uhub0: port 2 reset failed # Jan 24 12:10:21 mousse /bsd: sd3 detached Jan 24
