Why is my USB port a silly number like COM27?
Device Manager | pick the port | right mouse | properties | port settings | Advances
Yes but it says (in use) against the one I want?
Just select it. It whinges but it does it.
How do you fix it? Well it's no good just selecting them in turn as it only clears them until you reboot.
This seems to be a list of what ports are adopted by what virtual ports. HKLM/System/CurrentControlSet/Control/COM Name Arbiter
The ComDB entry is bits indicating COM1 (x01), COM2 (x02), COM3 (x04), are in use. Edit to 03 00... and only COM1 and 2 will be 'in use'.
This is all the devices that the usb driver has seen before. The vilian for me was the Prolific driver. You can't delete it but you can find its oemnn.inf file name in /Windows/inf/ and rename it. Look under VID_067B&PID_2303.
