TS-4200 Disabled USB Device Port

From Technologic Systems Manuals
Synopsis The USB Device port on the TS-4200 relies on a floating IO signal for the OS to determine whether the port is enabled or not.
Severity Minor
Class Software bug
Affected All un-patched TS-4200.
Status Kernel recompile required. See "workaround" below for patch.


The default TS-4200 kernel relies on a floating signal to determine the enable status of the USB Device port. As a result the port will work randomly or not at all on some TS-4200 systems. A kernel patch is required to fix this bug.


Download the current TS-4200 kernel sources from here, build and install the new kernel.
