Question about Computers & Internet
Thank you for taking the time to assist me. Much obliged. To answer your question "No," there is no yellow exclamation mark present next to the device, it continues to be known as "unknown device." Tis is the first use of this device, when I connect it to the keyboard port (where it gets power from) it comes to life, beeps and the lights flash. I downloaded a virtual serial com port software package from download.com. Prior to this I was unable to get it to work on any port. After installing that software it was opening all 8 ports so I am still a tad perturbed.
I look forward to any advice that you may offer.
Thanks again for your time.
1. Try plug in the device to the back of your computer instead of the front USB port (this is because some computers don't have enough power in the front USB ports)
2. Some USB 2.0 device are not backward compatible with USB 1.1 ports. Try plugging in with USB 1.1 and 2.0 port to see that's the cause of the problem.
3. Try downgrade all your USB port from 2.0 down to 1.1, you can do that in your BIOS.
4. if all failed, try the USB device on a different computer. Then you can determine if the USB device or the USB port is the culprit of the problem
