Hi
I try to install a USB lexmark M410 in two identical Redhat 7.1 PC.

One of them, under printer GUI, I have the option
/dev/usb/lp0 Then I can add the printer OK.

The other one, I do not see that option.
Yes, I use the same cable same known working printer for both.

Here is the dmesg

[root@buzzy /root]# dmesg | grep USB
usb-ohci.c: USB OHCI at membase 0xf895a000, IRQ 16
usb.c: new USB bus registered, assigned bus number 1
hub.c: USB hub found
hub.c: Maybe the USB cable is bad?
hub.c: Maybe the USB cable is bad?


[root@buzzy /root]# dmesg | grep hub
usb.c: registered new driver hub
hub.c: USB hub found
hub.c: 4 ports detected
/dev/vmnet: hub 0 does not exist, allocating memory.
/dev/vmnet: port on hub 0 successfully opened
/dev/vmnet: hub 1 does not exist, allocating memory.
/dev/vmnet: port on hub 1 successfully opened
/dev/vmnet: port on hub 1 successfully opened
hub.c: Cannot enable port 1 of hub 1, disabling port.
hub.c: Maybe the USB cable is bad?
hub.c: Cannot enable port 2 of hub 1, disabling port.
hub.c: Maybe the USB cable is bad?


Any idea ? Help Please
Thanks
