hi, i'm installing window xp in my aspire 4520, but my device manager still showing 1 unknown driver still haven install.. i dunno is which 1 because every driver i already installed.. but it keep showing. do anyone know about this ?

i install CIR driver le ... but still de same, really stress

i later found out is cir prob.. but i dunno how 2 deal wif it, sorry me comp noob
i try using the CIR driver dat i got from http://ronaldsoo.com/2007/08/31/acer-aspire-4520/, i can install it but still the same problem.. stress

wan 2 ask, if using XP sp3, will it affect the driver installation? because i cant install HID CIR

yes, i unzip and installed it, but then the device manger still showing unknown device in HID section. when i tried to update the driver from another folder, the XP logo testing warning pop out saying it did not pass the window logo tsting, further installation will might cause the system to be malfunction etc
