Ok, so I'm playing around with some code I found at this link which has a great tutorial and download for a hid wrapper in VS2010.[^]

I've created the template and currently trying to read from my hid, which is a USB sim card reader with a MA101 usb bridge driver.

All seems to be well, it recognises the VID and PID but when I read from the device into a buffer I just get blank data.

When using the proprietary software for the usb reader it connects and reads data from the sim fine. So, is there a certain mode I have to be in, a certain command I have to send first?

Any advice appreciated.

Thanks, Col
