    Yes. The computer recognized an "unknown USB device" and proceeded top print gibberish on my other USP Inkjet.

  • lbrande Aug 23, 2008

    I had already tried that, but the system sends the print data to the HP
    7410 that is also installed. The HP 2100 is not a PnP printer,
    and the Rosewill RCW-615 cable apparently needs a driver in order to
    work. Rosewill does not have an XP driver.

Sorry that I have nothing to add to this besides stating that I am having the same problem with the RCW-615. I am trying to connect a Epson 570e dot matrix printer to a HP Proliant server that has no parallel nor normal PCI slots.

So far I have tried it in 3 other PC's all 2k or newer and none work. The worst part is a parallel to usb cable is really only useful on newer systems as anything that has 98se will have a parralel port.... On the upside Rosewill and Newegg are very helpful and if the replacement they are sending doesn't work they've promised a refund.

I have a Rosewill Wifi usb adapter that used to work on my Dell PC but I had to have the pc cleaned up due to virus. Now I can't get wifi to work. If I had an install disk, I've lost track of it.

you need to give the exact model number written on a label on the back of the adapter as there are a lot of different models made by rosewill

you can try looking here if you can find it

if you cant reply with the model number and i will give you the download link

Drive not recognized under Vista Home Premium 64-bit

I have seen drives not recognized for a few reasons. Bad drives, drives not jumpered correctly or full-disk encryption was used on them. Here are my thoughts:
Try making sure that the drive is jumpered to Master. Should be a jumper on the back of the drive.
Make sure you did not encrypt the hard drive using full disk encryption.
I use an USB IDE drive enclosure when recovering customer's data using a Vista computer and have not had any issues other than the ones mentioned above.
Let us know if this helps or what you find out.

Having trouble installing HP Photosmart All in One Printer. Model C5280. Near the end of installation it ask's for printer to be connected via USB cable. Msg comes up on screen 'USB Device not recognized'...

Dear Sir:

It seems that the printer has gone bad because when you get this message 'USB Device not recognized' it means that the usb device connected to the computer is defective however I would suggest you to connect this device to another computer and if you are getting the same error with the other computer.

Please contact hp support they should be able to help you with this.

Please feel free to get back to me If you need any further assistance.

My Dell Dimension 2400 does not recognize plug & play for my HP OfficeJet Pro L7650 all-in-one. If I add the all-in-one manually, the computer says it's offline. I've uninstalled & reinstalled the...

My solution was very simple...I just threw my computer out the window! Seriously, the problem has not been seems that several types of Dell computers (in my case, the Dimension) have a problem with HP all-in-ones with regard to the USB 2.0 having enough power to recognize the plug and play option when installing the HP product. Dell's only solution (that I could find) is to operate the HP product thru a USB I guess I'll try that first and, if it still doesn't work, I'll probably just upgrade to a newer non-Dell Dimension computer.
