Might be you're not getting the interrupts. Have a look at
http://www.linux-usb.org/FAQ.html#ts6
Thanks for the pointer.
I've tried everything I can find relating to interrupt stuff and other items mentioned in the FAQ. I've turned off ACPI in the BIOS. I've tried fiddling with the plug and play setting, I've tried manually assigning interrupts to various devices (in addition to the default auto.) I've tried booting the kernel with noacpi, pic-noacpi, and acpi=off. I've tried the front and back USB ports (looks like only 2 of the 3 USB controllers are connected in my configuration.)
I get many different results at different times. None of them seem to be terribly consistent, or particulary tied to the configuration change I'm trying at the moment.
Messages of this type are very popular when I plug in the device after the OS is up:
usb-uhci.c: interrupt, status 2, frame# 1693 usb_control/bulk_msg: timeout usbdevfs: USBDEVFS_CONTROL failed dev 3 rqt 128 rq 6 len 18 ret -110 usb_control/bulk_msg: timeout usbdevfs: USBDEVFS_CONTROL failed dev 3 rqt 128 rq 6 len 18 ret -110 usb_control/bulk_msg: timeout
In particular, I get dozens of the control failed messages.
This is the equivalent in /var/log/messages

Dec 7 14:21:59 adsl-64-167-139-62 /etc/hotplug/usb.agent: ... no modules for USB product 4572/4572/100
During this time, the interrupt count for the interrupts on those devices is going up about a thousand a second, and I get 5-20 thousand interrupts total byt the time it quiets down. After that, no more interrupts unless I replug it in again. Of course, I'm pointing the remote at it and presing buttons during various stages, to no effect.
Right this sec when I plug it in with Linux booted, I get:
usb.c: USB disconnect on device 00:1d.0-1 address 6 hub.c: new USB device 00:1d.0-1, assigned address 7 usb-uhci.c: interrupt, status 2, frame# 521
Shortly folloed by screenfuls of:
usb_control/bulk_msg: timeout usbdevfs: USBDEVFS_CONTROL failed dev 7 rqt 128 rq 6 len 18 ret -110 usb_control/bulk_msg: timeout usbdevfs: USBDEVFS_CONTROL failed dev 7 rqt 128 rq 6 len 18 ret -110
I also failed to include lspci -v output before:

(This is with me having assigned an IRQ to all the PCI devices.)
Oh, and when I do boot with noacpi, I tend to get this:

So, at least that's one consistent difference, which tends to validate the ACPI interference, maybe?
Any other thoughts on what else I might try to resolve the problems?
