USB PIC18F compendium to begin

[cj_tomekk]

Hello,
I'm building my first USB device on 18F2550. Firstly I've tried the example from manual and... **** happens :roll:

Main problems are:
1.Unknown USB device on Windows occures mostly
2.If it goes ok and I see the device, when trying to talk to it I get bluescreens sometimes on microchip.sys or usbd.sys
3.No communication is made (bytes send and recieved using echo PIC code)
4.With MCHPFSUSB and demo app in Example Applications\Borland_C\Example 02 - Run-time Linking i get an error 31
5.I've tried adding LEDs on port B to see what happens inside and code usually stops in place of HID_Read and stay there for a minute or so. While using example app mentioned in point 4, swithing option 3 and 0 for instance a LED change cycle occures.
6.What should I be aware of in case of configuring PIC for USB?
7.How to set descriptor to use bulk ransfers (as fast as possible)? I've seen people have problems with 64k limit...
