Usb don't work on my acer5100. i will try diferent OS (xp, ubuntu) but usb devices not recognized. any solution?

I found that often, external hard drives just don't have any active partitions and thus don't show up in Windows. Go into the control panel, administrative tools, computer management and then the disk manager and see if it has a partition. If it's just unallocated space, right click and make one.

XP is a dead OS.
100% dead. and not supported now. by MS or HP.
but XP needs SP3, or USB will be bad
XP always had bad USB for years until , all patches were done.
The USB on XP are horrible.
you need good USB so all devices are PnP recognized
and negotiated currents (power) is working
and USB2 currents are weaker than USB 3.
and is key to making any motor driven HDD work right.!!

Dead as a door nail and no more security patches ever again.

please you can try a diferent usb port.
if that dont work, then shut down and resart your system with device plugged in.

if it still don't work, reinstall driver if device isn't plug and play

In Ubuntu, go to Administrator/Hardware Driver Update. It will run an update to check drivers available against your hardware. BTW new version of Ubuntu available at the end of the week. Ubuntu Upgrade If that's unsuccessful, run a normal Ubunto Update to do a driver/support search. In XP, boot up,, insert your install disk and right-click on My Computer/Properties/Device Manager. There is an option at the top to "Scan for Hardware Changes". It should recognize the USB hardware. When it asks where to get the drivers, point it to your installation disk which should have all of your USB drivers on it.
Best of luck and enjoy Ubuntu!

email me and i will send the driver in an attachment file.please not though that the hp 740i burner is an internal I D E supported drive not a USB. as long as its a 740 model the driver should work, wether its usb or ide is up to the computer to associate it with.

Check lsusb and see the list if u can find the root in the list

u better install windows 7 or updated os in ur system bcoz microsoft had stopped the updates for xp os. so i can say u to install latest updated os to rectify ur problem

It has the latest mouse driver (logitech setpoint 4.0). Before installing Ubuntu the setup worked w/ SUSE/XP using GRUB dual boot. After installing Ubuntu XP does not see the usb mouse. Even Logitech setpoint does not have the mouse setup/configuration option. It appears that at boot it does not recognize the mouse or disables it. The BIOS has the usb keyboard and mouse enabled. Currently, I have two mices one for xp and either mouse will work under Ubuntu.

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;

HKEY_LOCAL_Machine\SYSTEM\CurrentControlSet\Services\Usb

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.
