Hi, this morning I found both USB-ports on the back of my Iyonix weren't working. Finally I unplugged the power from the hub which I use and I the hub the took power from the Iyonix and told it was present again. However USB info tells me that there are only 3 buses while I seem to recall that there should be 4. Is this so? *usbbuses Transfers (3 buses): Bus Control Isochronous Bulk Interrupt 1 836 0 0 13052 2 1119 0 0 9631 3 1362 0 0 111 *usbdevices No. Bus Dev Class Description 1 1 1 9/ 0 NEC OHCI Root Hub 2 2 1 9/ 0 NEC OHCI Root Hub 3 3 1 9/ 0 EHCI root hub 11 2 4 0/ 0 Logitech USB-PS/2 Optical Mouse 12 1 2 9/ 0 Genesys Logic USB Hub 13 1 3 0/ 0 Chicony USB Keyboard Any suggestions?
