in [Hardware]

From: kumar_gr.78 on 3 Jan 2008 14:16 Hi, I've an DVD writer, Sony DVD RW DRU-190A and an IBM thinkpad R51 with Windows and Linux FC6. I use a USB 2 enclosure to house the DVD writer and connect to my laptop using its USB ports. Problem is that the drive doesn't seem to get recognized by windows. I plug the samething into my desktop and the drive gets recognized correctly there. I've had no luck with Linux either, Linux seemed detect the drive correctly, but didn't suceed in writing/reading from any disk I put in. It seems to report the following errors: kernel: usb 4-4: new high speed USB device using ehci_hcd and address 5 kernel: usb 4-4: configuration #1 chosen from 1 choice kernel: scsi2 : SCSI emulation for USB Mass Storage devices kernel: Vendor: SONY Model: DVD RW DRU-190A Rev: 1.63 kernel: Type: CD-ROM ANSI SCSI revision: 00 kernel: sr0: scsi3-mmc drive: 125x/125x writer dvd-ram cd/rw xa/form2 cdda tray kernel: sr 2:0:0:0: Attached scsi generic sg0 type 5 and then when I try to burn I get: kernel: usb 4-4: reset high speed USB device using ehci_hcd and address 5 last message repeated 2 times The speed detected also keeps varying each time I connect the drive. Sometimes I get: kernel: sr0: scsi3-mmc drive: 5x/48x writer dvd-ram cd/rw xa/form2 cdda tray The errors also vary: kernel: usb 4-4: reset high speed USB device using ehci_hcd and address 7 kernel: usb 4-4: device not accepting address 7, error -71 kernel: usb 4-4: reset high speed USB device using ehci_hcd and address 7 kernel: usb 4-4: device descriptor read/64, error -71 kernel: usb 4-4: device descriptor read/64, error -71 One other strange thing that I noticed was that when I connect the drive, the USB keyboard also begins to act strange. Sometimes it just doesn't respond to keystrokes or keeps giving multiple instance of a keystroke when I just press it once. I've also tried unplugging all USB devices and just having the DVD drive, that didn't work either. The drive when connected to a desktop directly to IDE works fine. When it is connected to a desktop with the USB enclosure also works fine. Its just that it doesn't work with my laptop. I tried with a another laptop R52 as well, but that didn't work too. Both windows and Linux fail. Windows reports that a USB device attached has malfunctioned and windows is unable to recognize it. It shows up in the device manager as unknown device. The USB enclosure uses USB 2 and has an external powersource. It gives 12V, 2A. While my DVD writer requires 12V, 1.5A I use Windows Xp SP2 and Linux fc6 (2.6.18-1.2798.fc6). Any pointers on what could be wrong would help a lot. thanks, Kumar

Is the driver for this USB enclosure installed correctly in the laptops? Can you try connecting your desktops harddisk to the USB enclosure connected to the laptop and check if it's working fine? -- Strider ------------------------------------------------------------------------ Strider's Profile: http://www.techtalkz.com/member.php?userid=1 View this thread: http://www.techtalkz.com/showthread.php?t=379429 Posted @ http://www.techtalkz.com - Technology & Computer Troubleshooting Forums
From: powersupplycables on 7 Jan 2008 05:22 Kumar: The problem maybe because power supply is not powerful enough to run the DVD along with all the devises you have.The laptops just don't have the power that desktops have. When you don't have enough power, your devices suffer, that's why your keyboard acts unexpectedly too. You may check the power consumption of the DVD and compared to what you have on your laptop.
