Hi
I just got ASRock Z77E-ITX motherboard to my test bench and got it working nicely except one thing. The machine won't detect TBS6280 TV Tuner Card. The device won't come to Windows 7 device manager. I have updated BIOS to 1.30 and tried it with different settings, but it's still not working.
This problem is the PCI-E 1.0a compatible problem and someone at TBS should contact Asus and ASRock immediately.
TV Tuner Card is working with Dell Optiplex GX620 and ASUS P8Z77-V Deluxe. It isn't working with ASUS E45M1-I Deluxe (BIOS 0306) and now ASRock Z77E-ITX (BIOS 1.10 and 1.30).
EDIT: I can confirm that TBS6280 is working with Asus Maximus V Gene (in PCI-E x16 and x4) and ASRock Z77 Extreme4 (in PCI-E x1)
