View Full Version : [SOLVED] 9.10 doesn't recognize my hdpvr

I have two hdpvr's on my system. Under 9.04, they worked fine once I installed the newest v4l development tree. Under 9.10, they're not recognized at all, even though the hdpvr is now included automatically. When I do a lsusb, there is a 10-15 second delay before listing, and then the list doesn't include the devices. In /var/log/syslog, I find the following:


syslog:Dec 7 15:41:50 jivo kernel: [ 248.828286] usb 4-2: FTDI USB Serial Device converter now attached to ttyUSB0

I think, though I'm not sure, that that is one of the hdpvr devices. What is error -110, and what should I do about it?

Thanks for any help!

I tried running 9.10 with the old 9.28 (?) kernel, with similar results. I still get no video devices, and I see the error -110 msgs in syslog. On the old kernel, lsusb gives no output, but also no delay. 'lsusb -t' shows the following:


jerry@jivo:~$ lsusb -t
/: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=ohci_hcd/6p, 12M
|__ Port 1: Dev 2, If 0, Class=hub, Driver=hub/4p, 12M
|__ Port 3: Dev 4, If 0, Class=HID, Driver=usbhid, 1.5M
|__ Port 3: Dev 4, If 1, Class=HID, Driver=usbhid, 1.5M
|__ Port 3: Dev 4, If 2, Class=HID, Driver=usbhid, 1.5M
|__ Port 2: Dev 3, If 0, Class=vend., Driver=ftdi_sio, 12M
/: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=ohci_hcd/6p, 12M
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=ehci_hcd/6p, 480M
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci_hcd/6p, 480M

Going back to the default kernel, 'lsusb -t' gives:


jerry@jivo:~$ lsusb -t
4-2:1.0: No such file or directory
/: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=ohci_hcd/6p, 12M

|__ Port 2: Dev 3, If 0, Class=vend., Driver=, 12M
/: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=ohci_hcd/6p, 12M
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=ehci_hcd/6p, 480M
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci_hcd/6p, 480M

Any ideas?

It works now. I think the problem was caused by the fact that I had the v4l development tree with hdpvr working on 9.04 before upgrading.

I'm not sure exactly what fixed it. I rebuilt the development tree and installed it. No luck. I uninstalled it (make rminstall). No luck. I reinstalled the linux kernel via synaptics. No luck. Then I powered down both hdpvr's, and repowered them. It worked! No idea why. I had tried pulling and replugging the usb cords several times, but that hadn't done the job.

Anyway, it seems to be working now, but upgrading to 9.10 was far too adventurous. Maybe, if you're about to do the upgrade and have built v4l, uninstall it and power down your hdpvr(s) before the upgrade.
