This has potential to add a tiny USB device through the unused larger PCIe slot inside the tablet. (Assuming you're not already using it for 3G.)
The internal PCIe slot did recognize my Intel 5350 WiMax chipset, as a USB device. Just couldn't do anything with it. So, theoretically, we could use this slot for tiny USB sticks, wireless mice and whatever else this kernel is built to support.
I'll see if I can find a local distributor in the USA...

Erg. It appears the spec for PCIe is only 3.3 volts, not 5, so that would limit a number of devices...
OTOH, it's cheap enough to test and the risk of bricking your tablet is low.
I'll likely order one next week and let you know how it works out...

This looks promising. I requested a quote. The chipset uses the USB bus.

I wonder if other miniPCIe cards would work ?
For example, something to fix the rubbish GPS that comes with the TPT
An extra SSD

OK, I just received a USB port and a mini T-Flash adapter for the internal PCIe port from the Chinese company. (They shipped REAL fast, so I recommend them.)
And they almost work...
The kernel recognizes both cards/drives just fine as /dev/sg0, BUT unfortunately, I don't have root, so I cannot mount or do anything with /dev/sg0.
External USB sticks show up as /dev/sda, recognized and mounted automatically. Unfortunately, Lenovo has not provisioned for /dev/sg0...
So much potential in this tablet, locked away, just out of reach... sigh...

Actually, I'm confusing myself...
I do see /dev/sda there... And it matches the size of the USB stick...
But it's not being mounted...
So, hold on to your hats, perhaps I need to format it differently... :/

Enh, same USB stick works fine externally, but not internally, despite being /dev/sda in both cases.
Not sure what's different between the two, unless there are rules to limit USB mounts only on a specific USB hub?
Oh well, it was worth trying...

LOL That's why I always use darn. I don't normally use darn, but just knew anything more would be edited.
