Public bug reported:
lsusb incorrectly labels a device using the product name from a previous
device.
In the listing below, the incorrect product name on the second 04d8:fee9
device ("Microsoft® LifeCam HD-5000") is a copy of the product name
of the first device in the list:
$ lsusub -s 3:
Bus 003 Device 002: ID 045e:076d Microsoft Corp. LifeCam HD-5000
Bus 003 Device 009: ID 090c:6300 Silicon Motion, Inc. - Taiwan (formerly
Feiya Technology Corp.) Kingston Reader
Bus 003 Device 007: ID 0451:8142 Texas Instruments, Inc. TUSB8041 4-Port Hub
Bus 003 Device 019: ID 04d8:fee9 Microchip Technology, Inc.
Bus 003 Device 011: ID 04d8:fee9 Microchip Technology, Inc. Microsoft®
LifeCam HD-5000
Bus 003 Device 006: ID 03eb:0902 Atmel Corp. 4-Port Hub
Bus 003 Device 013: ID 0bda:2838 Realtek Semiconductor Corp. RTL2838 DVB-T
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Device 04d8:fee9 is not a Microsoft device.
Below is a verbose listing of the device that displays the wrong product
name. You can see that "Microsoft" doesn't appear anywhere in the
verbose listing, except incorrectly on the title line. Perhaps lsusb is
forgetting to clear the product title string before listing each device,
so a device that is busy or doesn't report a string gets a previous
device's string?

The 04d8:fee9 device is in active use, which appears to interfere with
lsusb getting all the details. Also, using lsusb interferes with the
use of the device, causing "Protocol error" problems when trying to do
usb_set_configuration(), and also this error:
kernel: [680110.235892] xhci_hcd 0000:00:14.0: Trying to add endpoint
0x1 without dropping it.
