HI I installed Ubuntu 9.1 on my Acer Aspire 5102 WLMi laptop computer.
AMD 64x2 mobile Tec
I have not been able to get the usb ports my webcam and my blue tooth to work. I have a hardware program and it identified that I have ATI usb hub but it also says I have not power to them?
Funny thing is my sd card reader works so for now this is the only way I can get info into my machine beside the cd and downloading.
Not sure what else to do any suggestions?
Here is the terminal coding from putting in what is suggested.

Are there any settings in the BIOS to enable the USB ports?

Sorry I not sure how I check the settings in the BIOS to enable the USB ports?

Have you tried the 'wiggle' trick?

Otherwise, does 'gspca' show in the output of 'lsmod'?

this is what I got when following the link and then doing the lsmod.
peter@peter-laptop:~$ gsca
No command 'gsca' found, did you mean:
Command 'nsca' from package 'nsca' (universe)
Command 'gsc' from package 'gambc' (universe)

peter@peter-laptop:~$ nsca
The program 'nsca' is currently not installed. You can install it by typing:
sudo apt-get install nsca

Hope this helps you as it does not mean much to me... I did not install the packages as I don't know what they are for.

sdhci-pci is the module for the card reader which you say is working but I do not see any modules being loaded for USB.
usbcore
uhci-hcd
ehci-hcd
usb_storage
sd_mod

You can manually load the modules listed and see if the ports start working via the modprobe command i.e.
modprobe usbcore

Sorry not sure how to load modules listed and see if the ports start working... how do you do this as I cannot find an answer anywere?

Use the modprobe command i.e. (must be root)
modprobe <module name as listed above>
