I'd like to communicate to a device with USB RAW mode. The device is recognized as HID Compliant Device by Windows.So I created the .inf file with VISA Wizard. After the installation, the device shown up in the MAX with the appropriate resource name, but Bulk In Pipe column shown No Pipe Present and a error shown on the View Attributes column.Now I can send a command to control the device ,but can not receive data from the device.did I do something wrong? Please advise what should I do? Thanks!

I have had the same problem and also hope that someone can solve this problem.

HID sends data via Interrupt Pipe (0x81 in your screenshot).
Not having a bulk out or bulk in is not a problem for HID since HID has nothing to do with Bulk transfers.
I think you need to read up a bit on the USB spec. It's quite counter-intuitive at first.
