uhid write EIO

Hello all I am having trouble communicating with a custom HID device using FreeBSD 7.2. Open and read work fine, but write() errors with EIO My code works well with another HID that uses read and feature reports. Oddly enough, my Windows version using ReadFile and WriteFile works perfectly. Th

RE: uhid write EIO

Hi - quick correction - I had it working under 7.0, not 6.2, but I think I had a beta version of HPS' updated USB stack in there. Sam -Original Message- From: owner-freebsd-...@freebsd.org [mailto:owner-freebsd-...@freebsd.org] On Behalf Of Engineering Sent: Saturday, May 22, 2010

ugen write hangs on BSD 7.2

Hello all I am having trouble communicating with a custom HID device using FreeBSD 7.2. I was trying to use uhid, but it looks like it doesn't do interrupt out transfers. Open and read work fine, but write() errors with EIO The device is a simple PIC based IO board. When sent 64 bytes, it resp

Intro and question about High speed Isochronous

Hi all, this is Sam Zehr. I am an embedded systems programmer working on porting an app to FreeBSD. I'm afraid I'm no expert in BSD, or any *nix stuff, but I'm plugging along. My project requires high-speed isochronous transfer. At first, I thought, no problem. I got it working

Webcam ugen iso transfer problems

Hello I am having much trouble trying to read isochronous data from a UVC webcam. I understand that a full driver is being worked on right now, but I'd love to be able to get my 'mini-driver' which only does one frame rate working in the meantime. I have updated the USB stack with Hans Petter Sel

RE: USB Video Class support

I have a driver based off ugen. Hans Petter helped me get started on it - it should be using his new stack It was built for a custom embedded application, so the functionality is limited to just what I needed to get it going. It works with 7 out of the 10 different Chinese cameras I have laying a

Recommendations for programming HID in FreeBSD 9

Hi all, I hope this is the right place to ask this I am in process of migrating an embedded system from BSD 7.0 to 9.0, as we need upgraded video card drivers which will not compile on the old system. To confuse matters a bit, I believe it was 7.0 with some of HPS updated USB stack worked in. The
