From: Alan Stern Date: Wed, 20 Feb 2008 17:10:04 +0000 (-0500) Subject: USB: quirks and unusual_devs entry for Actions flash drive X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=274399d14f121d7676ecb75a461cfed6cf9e4cdb;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git USB: quirks and unusual_devs entry for Actions flash drive This patch (as1033) adds a quirks entry and an unusual_devs entry for the Actions Semiconductor flash drive. This device has a 64-byte string descriptor, which it doesn't terminate with a 0-length packet. Oddly enough, the reporter's logs show that when the device was plugged in at boot time, it changes its behavior completely -- it uses a different product ID, product string descriptor, and bDeviceClass.
