This is one of many pages discussing the issues of USB vs PS/2 keyboard latency. Apparently PS/2 keyboards will increase the latency by 5ms (at best) and USB by 1ms if tweaked. USB 3.x apparently gives the best latency. |__ Port 3: Dev 74, If 0, Class=Human Interface Device, Driver=usbhid, 1.5M I just ran "lsusb -t" on all of my systems to see what the speeds were and got lines like the above for all real keyboards and mice on systems I run, where 1.5M means 1.5mbit transfer rate (USB 1.0 low speed). The only keyboard/mouse devices I found using a higher speed are virtual keyboard/mouse devices on a Dell PowerEdge T320 system. Does anyone have USB 2.0 or better keyboard/mouse devices in their systems? -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ _______________________________________________ luv-main mailing list -- [email protected] To unsubscribe send an email to [email protected]
