Hi, when I read the USB Thumb Drive schematic, I found there is no pull-up resistors on D+ or D- (DMH, DMF, DPH, DPF pins). The overview says it is USB2.0 high speed and full speed Compliance (refer to USB Thumb Drive Reference Design|Freescale).

But if I plug it into computer, will it be recognized as high speed or full speed  and how?


Thank you in advance.
