Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I have an Acer(TM5720, 32bit, 2.3ghz, Intel Dual Core T7500) laptop. I use a dell USB wired keyboard and and HP Wired Mouse. Everything was working fine until this morning, i.e now Keyboard and mouse are detected on shell when i use this command lsusb, but still they aren't working/functioning at all. I used these commands too - dmesg|tail and lspci(i found the command on askubuntu.com itself).. But i don't understand what i can achieve from them in regard to my problem.

Any help is greatly appreciated

Regards Abhi

P.S - Space Key also doesn't work 20% of time while typing.. though, it does, if i press it consistently for more than 5-8 seconds..
