Yes, the intermittent nature of the problem is quite puzzling. I am quite thankful that you haven't given up on me yet. Thank you so much. > Here's another patch to try.

I think that I will begin to send you dmesgs from two or three tries from now on (if you want that information, of course), to see how the information in the logs change. Since this time there was much information that I didn't see in the former logs, I cut a lot less information than in earlier logs (for fear of cutting way too much). I included it below my signature. Thank you very much, Rogério. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Rogério Brito - [EMAIL PROTECTED] - http://www.ime.usp.br/~rbrito =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= drivers/usb/core/usb.c: registered new driver usbfs drivers/usb/core/usb.c: registered new driver hub drivers/usb/host/uhci-hcd.c: USB Universal Host Controller Interface driver v2.1 PCI: Found IRQ 9 for device 0000:00:04.2 PCI: Sharing IRQ 9 with 0000:00:04.3 PCI: Sharing IRQ 9 with 0000:00:09.0 PCI: Sharing IRQ 9 with 0000:00:0d.0 uhci_hcd 0000:00:04.2: UHCI Host Controller uhci_hcd 0000:00:04.2: irq 9, io base 0000d400 uhci_hcd 0000:00:04.2: new USB bus registered, assigned bus number 1 drivers/usb/host/uhci-hcd.c: detected 2 ports uhci_hcd 0000:00:04.2: root hub device address 1 usb usb1: new device strings: Mfr=3, Product=2, SerialNumber=1 drivers/usb/core/message.c: USB device number 1 default language ID 0x409 usb usb1: Product: UHCI Host Controller usb usb1: Manufacturer: Linux 2.6.1-2 uhci_hcd usb usb1: SerialNumber: 0000:00:04.2 drivers/usb/core/usb.c: usb_hotplug usb usb1: registering 1-0:1.0 (config #1, interface 0) drivers/usb/core/usb.c: usb_hotplug hub 1-0:1.0: usb_probe_interface hub 1-0:1.0: usb_probe_interface -
