Title: usb repeater
Post by: nanotechopolis_gr on June 27, 2013, 01:04:00 AM
hi guys !

i have mobile broadband internet connection but inside the house the signal is dead so i bought  10m usb cable to extend it out of the house but the problem is that the communication between pc and usb device  sometimes stops ! after searching information about the little cables inside the usb i found that has 1) +5v 2)gnd 3)data- 4)data+ 5)shield ! if i make a circuit from capacitors + voltage divider + external power that will increase the power and the data-+ it will work?
any help its welcome!!

   sorry if i am out of robot topics

Communication stops because 10m cable is way beyond recommended 5m limit (for USB 2.0 (USB 3.0 recommends 3m cable)). What You should do is use USB hub in the middle of two 5m cables. Or You can look for USB-over-WiFi (https://www.google.co.uk/#gs_rn=17&gs_ri=psy-ab&tok=SLdrgYEZK_KxyvpO9KYVvQ&cp=10&gs_id=12&xhr=t&q=usb+over+wifi&es_nrs=true&pf=p&sclient=psy-ab&oq=usb+over+w&gs_l=&pbx=1&bav=on.2,or.r_qf.&bvm=bv.48340889,d.d2k&fp=1c467a56b757aebf&biw=1600&bih=815) solutions.

You can use a USB 2.0 extender cable, such as typically used to connect Kinect devices to Xbox consoles.
These are available at Amazon UK, which I presume you can order from in Greece.
