Hi there,
I need to get in concat with someone that can handle, test and review a
patch for TT-USB2.0. I've found that for certain high-bitrate streams,
the TT-USB2.0 sends more ISOCHRONOUS MPEG data than is specified in the
wMaxPacketSize fields. I have a USB analyzer capture which shows this
clearly. This of course won't be received at the USB host and packet
drops appear inside the stream. The solution is to use another alternate
setting. The technotrend chip has many of these. I've now tested using
alternate setting 7 instead of 3.
Alternate setting 7 allows transferring a maximum of 3 * 1024 bytes.
Alternate setting 3 allows transferring a maximum of 1 * 940 bytes.
