I'm seeing a similar USB problem with the latest experimental packages. Any operation in my personal tools triggers USB resets in my mouse:

It looks like the libmtp library is sending some usbfs command to all attached devices. This command is failing on two devices: 2-1.1.3 is a Contour Design Perfit Mouse 2-1.3 is an ATEN CS-1734 KVM switch During these failures, my mouse stutters across the screen. Device 1-3 is the MTP media player. The common denominator here is that the tools get a list of raw devices (via LIBMTP_Detect_Raw_Devices), then loop across them to match the friendly name before invoking a callback. -- ii libmtp-dev 0.3.5-1 Media Transfer Protocol (MTP) development fi ii libmtp-doc 0.3.5-1 Media Transfer Protocol (MTP) library docume ii libmtp7 0.2.6.1-3 Media Transfer Protocol (MTP) library ii libmtp8 0.3.5-1 Media Transfer Protocol (MTP) library ii mtp-tools 0.3.5-1 Media Transfer Protocol (MTP) library tools -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
