Windows doesn't require "drivers" downloaded to access SD cards and should have all you need already in the OS. If it doesn't see it when you plug it in make sure the USB port is active and has its driver installed. If you're still unable to see it the card may be damaged or need to be formatted in some other device.
Do you have a legit copy of windows, sometimes if the copy is (Backup) then Windows will purposely disable drivers.
If, its a genuine version, first try plugging your usb device into another usb port somewhere. Try powering down your PC and powering it back on. If these steps do not work, go to Start>Contro>Driver/Devices and look if there is any Yellow caution signs with the device plugged in. If so, click on it and follow the steps prompted to find the appropriate driver for your USB device. It will do a search by itself.
Hope this helps-
its a plug and play just connect to the sys and start working on it
but be careful that u connect the power to the Ext.HDD first and then after that connect it to the USB port
similarly safe remove from the Sys and remove it only after u see the msg It is safe to remove the USB drive disconnect the USB cable from the Sys wait for 20-30 secs ten power off the HDD for better performence of the Ext HDD
Win 98 does not support plug & Play USB devices unless the drivers are installed. Xp how ever does. you need to install the drivers to be able to used the device in win 98. since you did not get a driver cd, best would be to download the drive from the net. if you abl to give me more details of the device, i would be able to find the driver.
My Sony USB 4 GB flash drive will not work on my XP Microsoft OS. It had been working fine for about 3 months, now when I go to open it, it asks with what program do I want to us. However, it works just fine when I put it on a computer with VISTA. Got any suggestions?
If your sister is using a windows based operating system like 95 or 2000, you will need to install the driver for that. The OS cant read anyting until you install the driver for it. But Windows Xp does not need any driver installation. Because it all ready has bulit in. If you are using Windows Xp then the problem can be harder to find out.
If u are using Windows XP, try to install the driver just in case, then see if it works, if not then there can be a problem with the card reader. Try using this with other friends of yours. And see if the Chip is fine or not damaged.
1) One of your USB devices have faulted, or is causing a resource conflict (or similar) -- Remove all USB devices, and reboot.
2) Your USB chip/ports have been damaged. -- Find a spare HardDisk or bacjup your data and re-install Windows and see how that goes.
3) Your Power Supply Unit (PSU) isnt supplying enough power to your PC (usually caused by a Video card upgrade). Try a more powerful PSU ... 400watts should do the trick
4) Bad memory (RAM) can cause wierd problems. run memtest for an hour to make sure your memory is ok
It seems that many people are still getting the 'USB Device not Recognized' problem from time to time. Unfortunately there is no easy fix.
Firstly, it's recommended that you make sure every one of your motherboard drivers are completely up-to-date, but you probably already knew that.
In XP, after a USB port isn't used for a long while the USB driver built into the OS sets the OHCI controller to suspend. When you plug a device back in, it can sometimes fail to 'wake up' properly. This problem was supposedly fixed in SP1 but there is a related registry hack that may still be able to help.
Run regedt32.exe and navigate to;
Create the Usb key if it doesn't already exist. Under this key, create a new DWORD value called DisableSelectiveSuspend and give it a value of 1. Then restart the PC.
A long shot perhaps, but I recall having similar problems with a USB hub built into my Microsoft keyboard and adding this key seemed to solve it. It wouldn't hurt in trying .
Alternatively, removing all entries relating to USB in Device Manager and all associated USB drivers will force XP into refreshing the USB driver stack.
Begin by unplugging all USB devices, then use Add/Remove Programs in Control Panel to uninstall any USB driver software. Next, boot up into safe mode and go to Device Manager. Once in device manager make sure 'Show hidden devices' is checked under the View menu. Uninstall all device entries in this order;
1. USB peripheral devices (printers etc.)
2. HID and/or Composite USB (Human Interface Devices) You're using PS/2 input devices so you may not have this entry.
3. USB Root Hub(s)
4. USB Host Controller(s) (Universal or Enhanced Host Controllers)
Then boot back into Windows (not safe mode) and it should populate the Root Hubs & Host controllers again. Proceed to plug your USB devices back in, starting with your powered hub. Be aware that most USB printers and scanners need to have their drivers installed first before you plug them in.
Hopefully some of this may be of help, let us know how you get on.
