Trebalo bi da ce raditi.Po USB standard-u do 7 m ne treba pojacivac signala, mada meni se desilo nekoliko puta da mi nije prepoznao uredjaj... [fotokopir,ups...] a sa 'upredenim' usb kablom od 5m jeste..

Neznam odakle ti to ali ja cisto sumnjam da on sto ovo hoce da uradi bi radilo. Evo sta sam nasao na USB.org:

Q2: Why can't I use a cable longer than 3 or 5m?
A2: USB's electrical design doesn't allow it. When USB was designed, a decision was made to handle the propagation of electromagnetic fields on USB data lines in a way that limited the maximum length of a USB cable to something in the range of 4m. This method has a number of advantages and, since USB is intended for a desktop environment, the range limitations were deemed acceptable. If you're familiar with transmission line theory and want more detail on this topic, take a look at the USB signals section of the developers FAQ.
