Bug ID: 220127
Summary: USB devices sometimes(!) not seen at boot time
Product: Base System
Version: CURRENT
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: usb
Assignee: freebsd-usb@FreeBSD.org
Reporter: g...@unixarea.de
This is on CURRENT (r314251, amd64) on an Acer C720 Chromebook. I have two USB
devices (small sticks designed to hold a GnuPG CCID cards, see
https://gnupg.org/howtos/card-howto/en/smartcard-howto-single.html#id2503306
)which both show the following problem:
steps to reproduce
1. power-off the system
2. insert the USB device (the stick) into any USB port of the machine
3. power-on and let the system boot
Sometimes (statistically in two of three boots) the USB device is not seen by
the kernel, i.e. it takes 2-3 reboots to get it seen.
When the device was seen during boot, one can withdraw it and re-attach it
again. It is always seen again and works fine with the pcscd, the card daemon
from ports.
When the device was NOT seen during boot, it does not help to re-attach. It is
never seen by the kernel. Only re-boot helps.
When the device is seen, it shows the following lines during boot:
dmesg:
ugen0.2: <HID Global OMNIKEY 6121 Smart Card Reader> at usbus0, cfg=0 md=HOST
spd=FULL (12Mbps) pwr=ON (100mA)
ugen0.2: <Identiv uTrust 3512 SAM slot Token> at usbus0
The latter shows, when it was seen on boot, the following usbconfig output:
# usbconfig dump_device_desc
ugen0.2: <Identiv uTrust 3512 SAM slot Token> at usbus0, cfg=0 md=HOST spd=FULL
(12Mbps) pwr=ON (76mA)
bLength = 0x0012
bDescriptorType = 0x0001
bcdUSB = 0x0200
bDeviceClass = 0x0000 <Probed by interface class>
bDeviceSubClass = 0x0000
bDeviceProtocol = 0x0000
bMaxPacketSize0 = 0x0008
idVendor = 0x04e6
idProduct = 0x5816
bcdDevice = 0x0202
iManufacturer = 0x0001 <Identiv>
iProduct = 0x0002 <uTrust 3512 SAM slot Token>
iSerialNumber = 0x0005 <55511514602745>
bNumConfigurations = 0x0001
There is another issue, maybe related to this one here
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=219220 which should be closed
in favor of this new one or resolved later, when this one here is solved.
