[linux-dvb] Nova-T stick: device descriptor read/64, error -71

Hello,

I had a Hauppauge Nova-T Stick that worked with kernel 2.6.24 (and previous)
with all recent hg trees and firmware dvb-usb-dib0700-1.10.fw.

I now have a new Nova-T Stick which does not work.

The first one was bought about one year ago, the second one a couple of months ago.
The first one was identified as 70001, the second one as 70009.

Front sticker: "WinTV NOVA-T digital terrestrial TV stick"
Rear sticker:  "M/R:70009/C1B5 #4807"

When pluging the device, dmesg reports errors:

    usb 6-1: device descriptor read/64, error -71
    usb 6-1: device descriptor read/64, error -71
    usb 6-1: new full speed USB device using uhci_hcd and address 43
    usb 6-1: device descriptor read/64, error -71
    usb 6-1: device descriptor read/64, error -71
    usb 6-1: new full speed USB device using uhci_hcd and address 44
    usb 6-1: device not accepting address 44, error -71
    usb 6-1: new full speed USB device using uhci_hcd and address 45
    usb 6-1: device not accepting address 45, error -71

How should I interpret this?

lsusb does not report anything. Specifically on device 6-1:

    Bus 006 Device 001: ID 0000:0000

Kernel version: 2.6.24.4-64.fc8 (Fedora 8 latest kernel)
V4L source tree: updated Apr 14 2008 (+ make & install & reboot)
Firmware file /lib/firmware/dvb-usb-dib0700-1.10.fw present
Note: a PCI Nova-T 500 in the same system is working OK.

On a Windows XP system, without Hauppauge drivers, the device is seen
as "unknown device" with identification "USB\VID_0000&PID_0000\5&54F4B9C&0&2".
I have no idea what it means but vendor id 0000 and product id 0000 seem suspect.

Shall I assume that the device is simply broken? Any other idea?
