Hello Alan, Started playing with usbmon. I do exactly what is written in the /Documents/usbmon.txt I did configure it on target. I do not have it on host. I might decide to make it for host, since I have source code for Guest OS, I am using on the top of VMware. My problem is, when I configure usbmon on the target, I do NOT see any traces initiated from the host. So, if I do any tests from Linux USB Gadget Zero framework, from host, I do not see any traces in usbmon out file on target. But when I do type on target, usbmon records typing because keyboard is usb device. I guess, to do proper traces for USB Gadget Zero test framework I need to do usbmon on host side. Am I right? I used 0u to record all transactions on target. Thank you, Zoran -------------------------------------------------------------------------------------- Intel GmbH Dornacher Strasse 1 85622 Feldkirchen/Muenchen, Deutschland Sitz der Gesellschaft: Feldkirchen bei Muenchen Geschaeftsfuehrer: Douglas Lusk, Peter Gleissner, Hannes Schwaderer Registergericht: Muenchen HRB 47456 Ust.-IdNr./VAT Registration No.: DE129385895 Citibank Frankfurt a.M.
