During startup I see that udev loads the module 3 times, the apropriate dmesg entries are : 22 /var/log # dmesg | grep -i uhci_hcd uhci_hcd 0000:00:1d.0: UHCI Host Controller uhci_hcd 0000:00:1d.0: new USB bus registered, assigned bus number 1 uhci_hcd 0000:00:1d.0: irq 11, io base 0x00001800 uhci_hcd 0000:00:1d.1: UHCI Host Controller uhci_hcd 0000:00:1d.1: new USB bus registered, assigned bus number 2 uhci_hcd 0000:00:1d.1: irq 11, io base 0x00001820 uhci_hcd 0000:00:1d.2: UHCI Host Controller uhci_hcd 0000:00:1d.2: new USB bus registered, assigned bus number 3 uhci_hcd 0000:00:1d.2: irq 11, io base 0x00001840 usb 2-2: new low speed USB device using uhci_hcd and address 2 usb 3-1: new full speed USB device using uhci_hcd and address 2 usb 2-2: new low speed USB device using uhci_hcd and address 3 usb 3-1: new full speed USB device using uhci_hcd and address 3 Shouldn't it be enough to load the module only once ?

First: Yes, for every usb-controller function of your chipset uhci_hcd is tried to load. This is no error. Normally udev should only print the first try (but if all modprobe-calls are nearly at the same moment it could be that msg is printed multiple times). uhci_hcd is then loaded only once! See at lsmod. dmesg only shows that you have more usb-controller functions on the chipset.
