need help with finding bmRequestType in USB trace


Hello,

I have an trace of an USB communication with an magic trackpad, while some settings where changed.
https://github.com/robotrovsky/Linux...orded_data.zip

(Total Phase Data Center Software needed to open the traces)

Can someone point me in the right direction, which is the USB-setup packet and what the bmRequestType is? I think it sould be the greenish OUT packets and the bmRequestType might be the byte "53", but I cannot find the consecutive bytes, especially the "length" field does not match.
