this would be perfect. Here are my additions for the moment:

File: usb_quirk.c

	USB_QUIRK(TOSHIBA, TransMemory, 0x0000, 0xffff, UQ_MSC_NO_SYNC_CACHE),
	USB_QUIRK(VIALabs, USB30SATABridge, 0x0000, 0xffff, UQ_MSC_NO_SYNC_CACHE),

I think that I found the 'problem' i mentioned before. It was a typo. The two lines above work now on my machine. 

File: usbdevs

vendor VIALabs	 0x2109	VIA Labs

product TOSHIBA TransMemory	 0x6545	USB ThumbDrive
product	VIALabs	USB30SATABridge	0x0700	USB 3.0 SATA Bridge

If you could also add this:

product HUAWEI ETS2055		0x1803	CDMA modem

and in u3g.c

	U3G_DEV(HUAWEI, ETS2055, U3GINIT_HUAWEI),

This adds support for a very rare modem manufactured by Huawei and used by an ISP in Indonesia.

The modem is in use on an 8.3 machine. The two storage devices are only used since a few days as backup devices on my X220. It would be good if we find somebody else with the same devices for testing.

I still have to storage devices I did not get up and running yet.
