it is an NCP scanner. HWID = USB\VID_0403&PID_6001&REV_0400
The wallwart puts out 5V@500MA so pwr wise it is within USB2 specs.
The system is reporting a code 43.
If I plug this into ANY other USB port, USB3/2 or Root hub (USB2) it works.
It is reported as a USB Serial Converter under Universal Serial Bus controllers
driver is FTDI
If I plug ANY other usb device (flash drives, usb3 ext drive, CD Drive, even other usb 2 serial converters) in to these ports they work.
The ports r on a front panel bd with only a cap on the power leads.
I can't read the pwr in device manager since it doesn't report it under the usb root hub like others.
It generates the usb serial converter entry.
Otherwise it is a straight shot (4 wires x 2) from the MB to the board to the usb connector.
I have devices connected to other root hubs and they also work.
One would surmise that it is the connection from the MB to the device via that bd.
But then why do other devices work on both ports? they too use all 4 lines.
