Dear Sir, I have a Canopus ADVC 110 which worked very good with Windows XP. I use an Audio Software Pyramix where ADVC 110 is used to capture the video . Now I changed my operating system to Windows 7 32 bit. My OS recognizes the IEEE firewire port & the device, But still the Audio software shows as no firewire device found, hence not able to capture the video. In Windows XP the firewire port takes OHCI COMPLIANT IEEE 1394 HOST CONTROLLER & the device is AVC COMPLIANT DV TAPE RECORDER/PLAYER. In Windows 7 the firewire port takes LSI OHCI COMPLIANT IEEE 1394 HOST CONTROLLER & the device is AV/C COMPLIANT TAPE RECORDER/PLAYER. I changed my IEEE driver to OHCI COMPLIANT IEEE 1394 HOST CONTROLLER (legacy) & many other option's & same with the device options still no luck. Windows 7 shows driver installed properly. I checked with my Audio Software & there is no problem. Shifted back to windows XP & every thing works properly. Hence reaching onto the conclusion that there is a driver compatibility problem in Windows 7. Upgrading to Windows 7 is a must for me as my software gets updated. Sir I have been using Canopus ADVC 110 for years without any problem. Kindly let me for any device or driver updates or alternate option's to solve this issue. Eagerly waiting for your reply.
