Re: USB 1.0 to 2.0
The main difference between USB 1.0 and USB 2.0 if the speed of data transfer. The USB 1.0 can transfer data at a maximum speed of 12 megabits where as 2.0 has upto 480 Mbps. And all USB 2.0 devices are compatible with 1.0. Windows XP Home Edition and Windows XP Professional are both fully USB 2.0-compliant with the correct drivers.
So in your case you can use your USB 2.0 device i.e. PDA with the USB 1.0 but the speed will be lillbit slow.
Other wise you can purchase the PCI device which one of the expert has suggested you.

Unplug your USB cable from the hub, and plug it directly into the computer itself. That is #1 problem, ipods and iPhones don't like to work through USB hubs.
Alternatively, make sure that your charging cable is also a data cable. Some aftermarket cables for iPod and iPhone, especially those packaged with cig. lighter chargers, are charge only, and won't pass data.
If the same cable work on another computer, then you need to take a look at the USB functionality on the computer that is having issues.
These are fairly easy to install. It does require you to open the computer case. Remember to unplug the computer from the electricity before starting and properly ground yourself before touching any components in the case(static electricity can damage them). You should use a grounding strap that hooks to your wrist and attatches to the case or touch the case each time before touching any components. Once the case is open you will need to locate an empty PCI slot. Then use a screwdriver to remove the metal "Blank" that is covering the opening at the back of the computer. Then you can insert the new card with the USB ports facing the back of the computer and use firm but gentle pressure to insert the card into the port. Once the card is fully seated secure it with the screw you removed from the blank. Then plug the computer back in and run any installation software that came with the card if required and that is it.
This sometimes happen when static hits your system. Try this next time, hold the ipod/camera usb cord in one hand and the touch your pc with the other. (This will ground you to the pc) Then plug in your equipment. Good luck
Here are the steps to refresh/reinstall/uninstalling the USB ports on the computer.
The USB port needs to be refreshed to make sure that no other device has captured the USB port of the computer. The Mouse, video camera, your external USB hard disk; what ever it may be.
Follow the steps given below to refresh USB ports.
1. Right-click My Computer icon on the desktop, and then select Properties. 2. Click the Hardware tab. 3. Click the Device Manager Button. 4. Click the plus (+) sign to the left of Universal Serial Bus controllers. 5. Right-click the device listed under Universal Serial Bus controller and select Uninstall. 6. Click OK to confirm the removal of the device.
Please note, repeat Steps 5 and 6 until all the devices under Universal Serial Bus Controller are removed.
7. Shut down the computer.
CAUTION: Ensure that the Shut Down option is selected, instead of the Restart option.
8. Wait for 5 seconds and then restart the computer. When the computer restarts, a "Windows has detected new or added hardware" message window will open.
The above steps will refresh the USB ports.
Now connect the USB devices like mouse, video camera, your external USB hard disk...USB hubs...whatever you like and the drivers should install automatically.
Tip: It is always recommended to connect the main USB devices at the rear end USB port. As they require more power to initiate. The above steps are for XP operating system. When coming to the matter of Vista, please note the changes below: =========================== 1) Right-click Computer icon from the desktop , and then click Properties to open the System Properties window, and then select the Device Manager tab.
2) Click the Plus (+) sign next to Universal Serial Bus Controllers/Root hub.
3) Click the USB Composite Device entry to highlight it, and then click Remove. If a screen appears to confirm the deletion, confirm the deletion.
4) Disconnect the USB cable to the all-in-one, wait a couple seconds, and then reconnect the cable. This should restart Windows device detection (Plug and Play).
5) A New Hardware found screen may appear, click next through all of the screens that appear for the Wizard to install the USB Composite Device. Click Finish once the wizard completes.
Sounds like the card reader cables, USB cables, and Firewire, (1394) cables have been disconnected from the motherboard. I'm guessing granted, but it could have been when the TV card was removed, or perhaps when you were installing upgrades.
You've had the computer open, judging from the statement that you've upgraded it.
1.Computer off, and unplugged from the surge protector. Open the computer case. TOUCH the metal frame of the computer case, to relieve your body of static electricity.
2.You may have to use a flashlight. Look for the cables coming from the card reader. From the Front Panel. You may have to remove the Front Panel a bit, to peer in, and see which cables go to the card reader.
Finding these cables, follow them back to the motherboard. See if they're plugged in, plugged in tight, and if they are the right way around. Do the same for the firewire ports, and the USB ports. Follow their cables.
