Windows 7 x64 SP1
Sager NP9280/Clevo D900F i7 6GB RAM laptop
Laptop has USB 2.0 ports native, current X58 Express Chipset Drivers v184.108.40.2069
Rosewill RC-615 USB3 Expresscard Adapter w/ Renesas Drivers 220.127.116.11
SYBA SD-EXP20070 USB3 Expresscard adapter w/ Renesas Drivers 18.104.22.168
When attempting to play a standard def movie with Windows Media Player from a USB3 external DVD drive with a USB3 cable connected to either a Rosewill RC-615 USB3 Expresscard adapter or SYBA SD-EXP20070 USB3 Expresscard adapter plugged into a laptop with Intel X58 Express Chipset the movie will play for between 5 seconds and 6 minutes, then stop playing. The last frame received remains in WMP and the player remains in play mode indefinitely until WMP is shutdown with the red X or the USB3 cable is disconnected from the external USB3 external DVD drive. Choosing safely remove hardware from the tray results in no response, so at that point the USB3 cable is disconnected.
With the Deivice Manager open during testing the USB Mass Storage Device line item appears as expected, driver USBSTOR.SYS v6.1.7601.17577 and the DVD drive appears as expected, driver cdrom.sys v6.1.7600.16385. This behavior is observed with a Vantec CB-ISATAU3 SATA/IDE to USB3 Adapter attached to the DVD drive and a ByteCC ME-535U3 enclosure connected to the same DVD drive. Another DVD drive was also swapped in and the same behavior is noted.
If the ByteCC & Vantec devices are connected with a USB2 cable to the USB3 ExpressCard adapter the movie flows uninterrupted. Same results for the ByteCC & Vantec devices connected to the laptop's native USB2 ports. I have Thermaltake USB3 SATA docks running through the Expresscard USB3 adapters with no problem whatsoever. The connection of DVD drives triggers this problem.
The fact that the DVD drive will connect at USB3 speeds and play a movie for a short time (no windows slow connection tray error appears when connection is made) leads me to conclude that the hardware is working and that there is a software conflict which stops the data flow.
UpperFilters and LowerFilters have been removed from the DVD Class category which resulted in longer movie run times in the 2-6 minute range. I am stumped. Any ideas from the forum?
I have uploaded a .pdf file to my website containing screenshots of what is happening when the DVD drive is hooked up USB3. See south-paw.net/downloads/USB3 DVD Brief Data Flow.pdf
