![]() ![]() The problem I have is with one particular device (though there are some more I haven't tested yet so it's quite possible one of those may also exhibit the same problem). This is fine, as I can use my beagle protocol analyser to capture the initialisation packets from the genuine platform and then use the LibUSBDotNet library to replicate the remaining packets in the initialisation sequence and get them to start sending the packets correctly. Some of the devices will start up, be recognised by windows which will try to start them but fail to fully to initialise them leaving them in a half initialised state. Some of the devices will start up, be recognised by windows which will initialise and start them correctly using the generic HID class driver built into windows, the devices will then start sending correct data packets of the data to be tested. ![]() I have an application that needs to read and analyse a number of USB devices (not simultaneously, they are each run in seperate tests and could in theory be run on different machines).Įach of the USB devices is based on the USB HID class, and are manufactured by different companies, none of these USB devices are designed to be run on PC, but are meant for a different platform, however for the purposes of testing the devices the client has requested that the test application is run from a PC. I wonder if anyone can help at all, a bit of a specialist problem this. ![]()
