I haven't had a look at the bulk-mode drivers yet. I have played with the hid-mode drivers and now i am sticking with the iso-mode drivers. One problem i had with this example driver was for example that you have to insert a 0x42 in front of a DATA0-Packet answering a Control SETUP-packet to get this packet through the USBD-stack. Perhaps i haven't understand the usb-protocol correctly, but till now i haven't find any hint in the spec why this should be the case. After studying various example codes i just saw that i need this 0x42 - and all works. Have fun, Siegfried Schaefer Schaefer EDV-Dienstleistungen und Softwareentwicklungen
