I ask because the report descriptors are missing from the output, and this is typically what happens when lsusb is run as a normal user, not root. Also, the dmesg logs indicate that you weren't running the -stable kernel versions. It's possible that this problem has already been fixed in those versions. For the same reason, you might try running a 5.8 kernel. If none of those work, you can always try running git-bisect to find the particular commit which caused the problem to appear somewhere between 5.0 and 5.4. -- You are receiving this mail because: You are watching the assignee of the bug.
