So the curious thing is that it works like that: addr 1: UHCI root hub, Intel addr 3: AVerMedia USB Radio, AVerMedia Technologies (can write commands to /dev/ugen0.2) But not like that: addr 1: OHCI root hub, NEC addr 2: AVerMedia USB Radio, AVerMedia Technologies (writing to /dev/ugen0.2 fails with EIO) -- Dmitry A.

Need docs on USB driver development
Hi! I want to write driver for "AVerMedia Technologies" "AVerMedia USB Radio" FM tuner. Though it's HID device, I was not able to make it work through neither uhid nor ugen drivers (though I'm gonna do some more digging here). So I've decided to go level lower and write kernel driver for the device (for fun & new knowledge as well). I've taken ufm driver as a basis and now I have a driver that successfully attaches to a device, creates device node and reports some info, but I'm a but stuch with actually communicating with device. Neither arch handbook, nor developers handbook, usbd_* manpage and usb headers have any verbose information. Thus, I would be grateful for documentation on FreeBSD USB driver development. If you're curious, my current work is based on http://av-usbradio.sourceforge.net/index.php?show=reverse. Currently I try to send that 16 initialize bytes into the device. I set up pipe via usbd_open_pipe, then xfer via usbd_alloc_xfer and try to do usbd_bulk_transfer, but it fails with USBD_IOERROR and sometimes I end with my system unresponsible to keystrokes (though I can switch between consoles). Also advices regarding driver testing environemnt would be useful (fsck takes too much time). I can think of qemu which AFAIR supports USB devices and booting from NFS partition. -- Dmitry A.

Re[2]: usb/85067: [uscanner] Cannot attach ScanJet 4300C to usb device
The problem is fixed in 6.3-STABLE. ScanJet got attached as uscanner0 without any problems. But scanimage (SANE) currently needs it to be a generic usb-device (ugen) and ugen fails with the same problem as uscanner did it before. So, plese apply the same fix to ugen, as it was done for uscanner. And the world will be happy :) -Original Message- From: [EMAIL PROTECTED] To: [EMAIL PROTECTED], [EMAIL PROTECTED], freebsd-usb@FreeBSD.org Date: Tue, 29 Jan 2008 10:06:53 GMT Subject: Re: usb/85067: [uscanner] Cannot attach ScanJet 4300C to usb device > > Synopsis: [uscanner] Cannot attach ScanJet 4300C to usb device > > State-Changed-From-To: open->suspended > State-Changed-By: linimon > State-Changed-When: Tue Jan 29 10:06:34 UTC 2008 > State-Changed-Why: > Mark suspended awaiting patches. > > http://www.freebsd.org/cgi/query-pr.cgi?pr=85067 > ___ > freebsd-usb@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-usb > To unsubscribe, send any mail to "[EMAIL PROTECTED]" > ___ freebsd-usb@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "[EMAIL PROTECTED]"
