I assume you have UCHI support enabled in the kernel, either built in or as a module. If its a module, have you modprobed it? Plug in a usb device and then run 'dmesg' to see if the system recognizes it. Post the relevant lines from the dmesg output and someone may be able to help.
(I like to run 'dmesg' before I plug in the device and then again after to note any changes.)

Do you have scsi compiled in your kernel? My USB thumbdrive requires it. I think you need at least:
SCSI generic support
USB device filesystem
USB Mass Storage support
and possibly support for whatever type of memory you're trying to use (I have both sandisk options enabled... not sure if they're needed or not)
all found under Device Drivers -> USB -or- Device Drivers -> SCSI
From dmesg, it looks like your usb system is working okay... it finds the devices. I believe when your thumbdrive is working, it will be mounted on one of the scsi devices, e.g. /dev/sda1. dmesg will tell you where it is. e.g.:
Attached scsi removable disk sda at scsi1, channel 0, id 0, lun 0
Attached scsi generic sg1 at scsi1, channel 0, id 0, lun 0, type 0
USB Mass Storage device found at 2
As far as the printer... what does it do that indicates it isn't working? Are you using CUPS? Have you compiled in usb printer support, or modprobed it?
Oh, one more thing.... usb requires hotplug to work right... it looks to me like you've got it, but check for that in your kernel as well. Good luck!
I'm pretty new to all this also, and don't really know what most of that output means. The only other thing that comes to mind is that maybe your system doesn't have a driver for the card reader, although it seems like it should just be able to mount it like anything else...
