I believe so. How do I verify it?
I've tried to move it to the other on-board hub but without results.

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
# 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
scsi6 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 6
usb-storage: waiting for device to settle before scanning
