I saw you mentioning this before, but my knowledge of usb-management (let alone asynchronous urbs is small); where can I find info on this? Plus the fact, that I promised to try the kernel-mode progs... Ah yes, it keeps me from regular work.. Ciao too, Ok Duncan Sands wrote: >>What

It looks like glued together frames, I remember seeing a filler-cell with a normal pti of 0. According to what I find on internet, this should be negotiable with the isp, when a connection is up. I read something about the qos and the setting of a Maximum Burst Size...does that ring 1 or more

Still hacking along, guys; I made a simple pipe-version for the usb-read-part, but that gave no difference. In the meantime I found something else though: I always get a CRC-error, when the amount of data as read from the modem is abnormally (??) large, i.e. larger than 1696.. The regular s
