[OpenWrt-Devel] periodic task checking for usb flash media?

Hi,

I've got a custom board with an onboard USB flash media
interface. It works well, I can mount and access micro SD cards
nicely, and all that basic stuff.

However, card detection doesn't work. The USB flash interface is
Mass Storage Bulk Only, and on my desktop linux system, there's a
period task polling the device every two seconds, sending SCSI
"TEST UNIT READY" and "REQUEST SENSE" commands, and this happily
detects card insertions/removals, (after the next poll)

On openwrt, this doesn't happen. With usbmon I don't see any
periodic traffic. Calling "block info" manually reliably detect
any changes and gets new device nodes created, that works just
fine, but do I really need to call that periodically myself?

Is this how it's meant to be? Am I missing some important package
or config? I'm not asking about automounting, there's plenty of
wiki help and options for that, but how do I get the card to be
detected at all?

Sincerely,
Karl Palsson
