    Have you tried both ports?



    If you check My Computer> Manage> Device Manager, do the USB ports show up? Any RED X's in the Device Mamager, anywhere?

You can get a PCMCIA adapter with 4 USB v.2.0 slots on eBay. It requires power from the USB port on the laptop, but the pigtail connector is included. Works like a charm! Comes from China just like everything else in this country.

Your USB ports on your computer are plug and play. If you have issues with your USB port, it is port related, driver related or device related. The following solutions will help you identify the problem to resolve your USB port issues.
To Identify a Working USB Port
Begin troubleshooting your USB ports by checking Device Manager to see if your USB ports or hubs are working properly.

  1. Click the Start button. ClickControl Panel.
  2. ClickSystem and Maintenance.
  3. ClickDevice Manager.
  4. Double-clickUniversal Serial Bus controllersand check to see if all your USB ports, hubs and controllers are functioning correctly. Any devices not functioning will have a yellow exclamation mark in front of them.
  5. If Device Manager shows any USB ports, hubs or controllers are not functioning, check for updated drivers.

To Update the USB Port Driver

An out-of-date BIOS driver can create issues with your system recognizing the USB port.
  • Watch a Video on Steps to Update Bios on Your Computer.
    1. When the update process is complete, your computer will restart again to load the operating system with the new driver version installed.

Get usb ports to work


Usually you don't need to do anything for any Windows to recognized the USB Ports. I will say that if the for instance a flash drives is not seen that you make sure that works in another PC.
Sometimes Windows gets confused if many USB devices were used and then removed. Eventually it will stop recognizing anything that is inserted. If you know how to use the registry you can fix it but if you don't better not try it. Your other option is to re-install Windows.
As a technician I could some other things before re-installing so I will leave like that for now.

Does not recognize hard drive


1. try reseating it if that doesn't help you might have a hard-drive failure. the only way to be sure is trying a replacement drive (maybe you can borrow from someone or from another laptop - currently on laptops there are 2 types of hard drives IDE and SATA don't mix them up, they are not interchangable)

IBM ThinkPad T41 won't recognize USB 2.0 Ports (sees them as USB 1.1)


all available ports are not recognized? have you tried other known good usb devices on those ports?if other devices are recognized then it is an issue with the usb device you were first trying to hook. if not, then it may be the port issue or driver. so update chipset driver for your pc. use ibm's website to check for drivers of your pc.

There are several PCMCIA USB ports available, I have an IBM T20 and I bought a Belkin USB 2.0 card from ebay for under $20, it has 2 USB ports, (and I've seen them with up to 4) and most electronics store should have them. They also come with Firewire ports if you choose to go that route

Hey,

the other usb port is most likely used inside the computer possibly a memory card reader or other integrated device is using it.

if you can't find it on the laptop, then its internal.

Let me know if you need anything else.


Thanks,
Ekse

Wow, a lot of information but I'm unclear as to what you are trying to do.

Are you connecting the T20 directly to the T40 using a cat5 cable and then trying to access the internet on the T20 via the modem?

Connecting the two computer together using a normal cat5 will not work, you need to use a crossover cable otherwise you are connecting the send to the send and the receive to the receive.
You can also use a hub, a switch or a router if you have any of those on hand.

As for the modem, I suggest you unplug the telephone line from the modem and plug it into a phone and see if you can hear a dial tone. If you cannot hear a tone either the extension is bad (replace) or you outlet is defective. If you can hear a tone, the modem card may be defective.
