with the EHCI host controller driver loaded?
| I believe so. How do I verify it?
(see below)
and post /proc/bus/usb/devices (contents)

|
| I'm not sure. But I do know that it used to be *much* faster than this.
| My keyring is USB 2.0 capable and that's slow as well.

|
| Yeah, but I don't think it should be 30 kB/s.
|
| Some more details:
|
|
| The line that 'hald' puts in fstab looks like this:
|
| /dev/sdb /media/usbdisk vfat \
| user,exec,noauto,utf8,noatime,sync,managed 0 0
|
|
| The relevant parts of my .config:
|
| #
| # Miscellaneous USB options
| #
| CONFIG_USB_DEVICEFS=y
| # CONFIG_USB_BANDWIDTH is not set
| # CONFIG_USB_DYNAMIC_MINORS is not set
| # CONFIG_USB_SUSPEND is not set
| # CONFIG_USB_OTG is not set
|
| #
| # USB Host Controller Drivers
| #
| CONFIG_USB_EHCI_HCD=y
OK, EHCI answer is Yes.
| # CONFIG_USB_EHCI_SPLIT_ISO is not set
| # CONFIG_USB_EHCI_ROOT_HUB_TT is not set
| # CONFIG_USB_OHCI_HCD is not set
| CONFIG_USB_UHCI_HCD=y
| # CONFIG_USB_SL811_HCD is not set
|
| [...]
|
| CONFIG_USB_STORAGE=m
|
|
| What my dmesg tells me when I attach the device:
|
| usb 2-1: new full speed USB device using uhci_hcd and address 6
"full speed" is USB 1.x (12 Mbps, not high-speed 480 Mbps),
so the device is reporting itself as less than high-speed
or the USB descriptor parsing is missing it somehow (but it
works for a few hundred other devices).
