Pipe error

Hi, I'm getting the following error:

`Inf: DSO remote app is starting `...`
Inf: DSO remote app started.
Wrn: Exception in reading VID/PID -> invalid literal for int() with base 10: ''

Rules are added to udev rules.d and updated with relevant PID and VID. Any advice on how to proceed?

Same here on UTD2102CEL. The first occurrence of something like: self.handle.controlMsg(0x42,0xb1,None,index=0, value=0x2c) gives the error. I added a couple of extra printouts to locate the issue.
