From: user Subject: Re: [Parallels #67155] PD: usb device repeadedly connects and disconnects, Date: December 7, 2006 6:25:19 PM EST To: email@example.com hey there, this is NOT an external HD. this is a flash card writer. it does not have a power switch. as previously mentioned, it connects and, at times, even recognises the device but then disconnects and continues to do this repeadetly and indefinately. when paralles is off and the writer is connected mac os X does not see the writer(even in system profiler) (it is for windows based program). when parallels is on and i connect the writer it connects and disconnects. and i can then see it flash on the XP VM hardware list AND max os system profiler. usb is activated and i have tried both auto connect and regular mode. neither seem to fix the issue.... here is the manufactures website: www.jeppesen.com its called the usb skybound hardware. please help!

Please save your work in Guest OS and shut down Guest OS before continuing. When your guest OS is switched off please open Configuration Editor and make sure that USB Controller Status in Configuration Editor is enabled. If there are no USB controller please press the "Add" button in the Configuration Editor, click "Next", select "USB controller", click "Next" and then "Finish". Then please click "OK" in the Configuration Editor to save changes. After that click "Power On" (or Play) button to start Guest OS. Note that only two USB devices can be used by Virtual Machine simultaneously. Parallels Desktop automatically detects all the USB devices connected to your host computer and displays them under the Devices/ USB menu item and in the context menu for the USB controller () in the status bar. Those devices that are currently connected to the Virtual Machine are checked. Primary OS can not access an USB device while it is used by the Virtual Machine. Note that Parallels currently emulates USB 1.1, not 2.0. Support for USB 2.0 in scope for future versions. Current USB implementation doesn't allow to use certain USB devices. But you can connect your external HDD to Windows OS via Shared folder. Please read attached manual in order to connect your external USB HDD. Best regards, Christoffer.
