The endpoint descriptor stored in the device specifies the maximum latency period. For low-speed devices, the maximum latency can be any value from 10--255 ms. For full speed, the range is 1--255 ms. for high speed and SuperSpeed, the range is 125 Ms to 4.096 s in increments of 125 Ms. In addition, a high-speed or SuperSpeed interrupt endpoint with a maximum latency of 125 Ms can request 1, 2, or 3 transactions per interval.
I'm assuming that that capital "M" character is supposed to be the greek "mu" letter, i.e.,
or (I hope I count the zeros properly) 0.000125 seconds.
Somebody tell me yes or no. I think the number is supposed to be 125 MicroSeconds.
The ZIP archives contain a lot of PDF files. The USB 2 and 3 specification files itself are about 5 to 7 MB. If you are not going to write your own USB driver, you normally don't need the specs. Just have a look at the driver interface documentation. An example would be the MSDN page USB_ENDPOINT_DESCRIPTOR structure[^] which also answers your initial question.
