I had issues installing a USB dongle to my mac a few weeks ago. Im worried i messed around with the drivers a bit back then.
When I next plugged in my arduino pro mini (it has been working for a long time) I was unable to upload my sketch. I could receive serial data through the serial window and everything appeared to be working fine but I couldnt upload anything. I found one site that suggested reinstalling drivers. I tried this, installing the driver recommended for my UART board, and now my computer recognises it but the arduino software does not. If I go into terminal with the USB plugged in I see this (after typing system_profiler SPUSBDataType)
CP2102 USB to UART Bridge Controller:
Product ID: 0xea60
Vendor ID: 0x10c4 (Silicon Laboratories, Inc.)

but in the arduino software the only serial port available is bluetooth.
Any suggestions?
