can't get debug descriptor: Resource temporarily unavailable

That's for the same reason why there's (error) opposite iManufacturer and iProduct in lsusb output (string descriptors are missing on the device). What's the full uclogic-probe output?

I'm having a similar issue, my uclogic-probe output is:
Failed to get manufacturer string descriptor: Pipe error (ERROR_PIPE)
While my lsusb is:

Some background in my case, I'm running on Ubuntu 16.04 with kernel 4.4.0-137-generic and my tablet was working ok until this weekend.
