Well, I just tried plugging the drive into one of the ports that come right from the motherboard and the diff relative to what I saw earlier is the following: --- /root/dmesg-no-devices-plugged.txt 2003-11-13 20:58:06.000000000 -0200 +++ dmesg-drive-plugged-unplugged-plugged.txt 2003-11-13 21:41:37.000000000 -0200 @@ -228,3 +228,30 @@ ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A drivers/usb/host/uhci-hcd.c: d400: suspend_hc +drivers/usb/host/uhci-hcd.c: d400: wakeup_hc +hub 1-0:1.0: port 1, status 101, change 1, 12 Mb/s +hub 1-0:1.0: debounce: port 1: delay 100ms stable 4 status 0x101 +hub 1-0:1.0: new USB device on port 1, assigned address 2 +usb 1-1: new device strings: Mfr=1, Product=3, SerialNumber=0 +drivers/usb/core/message.c: USB device number 2 default language ID 0x409 +usb 1-1: Product: USB Embedded Hub +usb 1-1: Manufacturer: Leading Driver Co.,LTD. +drivers/usb/core/usb.c: usb_hotplug +usb 1-1: registering 1-1:1.0 (config #1, interface 0) +drivers/usb/core/usb.c: usb_hotplug +hub 1-1:1.0: usb_probe_interface +hub 1-1:1.0: usb_probe_interface - got id +hub 1-1:1.0: USB hub found +hub 1-1:1.0: 2 ports detected +hub 1-1:1.0: compound device; port removable status: FF +hub 1-1:1.0: individual port power switching +hub 1-1:1.0: individual port over-current protection +hub 1-1:1.0: Port indicators are not supported +hub 1-1:1.0: power on to power good time: 100ms +hub 1-1:1.0: hub controller current requirement: 100mA +hub 1-1:1.0: local power source is lost (inactive) +hub 1-1:1.0: no over-current condition exists +hub 1-1:1.0: enabling power on all ports +hub 1-1:1.0: port 1, status 101, change 1, 12 Mb/s +hub 1-1:1.0: transfer --> -75 +usb 1-1: control timeout on ep0in - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - So, it seems that my drive indeed has an embedded hub in it.

Thank you very much for your attention, Rogério Brito. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Rogério Brito - rbrito@ime.usp.br - http://www.ime.usp.br/~rbrito =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
