Hum, from PIC32MX1XX/2XX datasheet p121:
Quote:The PIC32 USB module includes the following
features:
USB Full-speed support for host and device
Low-speed host support

The PIC in bootloader, so as USB Device only support USB Full Speed, the Low Speed is when you use the OTG feature (PIC as USB Host).

The thing is that all you said is true for example for PIC18F26J50, with it you can use internal oscillator without any tricks, only with config bits, and yes microchip says the internal oscillator is good for USB Low Speed.

Maybe you are confusing it, or maybe it's me Wink

For example I used the internal oscillator of PIC18F26J50 for USB FULL Speed and Low Speed without problem, also used for example the internal oscillator of PIC24FJ64GB002 for USB FULL Speed, all with config bits only.

Only 8bit PICs support USB Low Speed as USB Device, for 16bit and 32bit you only have USB Full Speed.

This is only what I think, of course I may be wrong Smile

( change JPG to 7z as the forum don't accept this type of file ).
