Re: Kernel 3.16.0 USB crash
Ok, thank you Hans. When I connect my external USB disk I've 30 seconds before my laptop freezes: with top command I cannot view nothing: no abnormal cpu usage, no any strange memory usage. If I remove disk before 30 seconds my HP EliteBook 850G1 keeps working as usual. Can I use these 30 seconds to extract some informations that help to determine what's the problem? How? /var/log/syslog and dmesg haven't any messages. System lock is complete: also key CAPS LOCK does not work anymore. I've tried without X: when computer locks 3 lines appear on console that are not registered on syslog, I've copied them on paper.

This way, the code will be full of #ifdefs. Is the following really what
you want? If you want to have it without #ifdefs, then I don't think it
is a good idea to offer users the usb-gadget trigger on systems without
usb gadget support.
#define BLINK_DELAY 30
static unsigned long usb_blink_delay = BLINK_DELAY;
enum usb_led_event {
USB_LED_EVENT_HOST = 0,
USB_LED_EVENT_GADGET = 1,
};
#ifdef CONFIG_USB_GADGET_LED
DEFINE_LED_TRIGGER(ledtrig_usbgadget);
#endif
#ifdef CONFIG_USB_HOST_LED
DEFINE_LED_TRIGGER(ledtrig_usb_hcd);

Re: Kernel 3.16.0 USB crash
I must make a correction to what I said earlier: on kernel 3.16.1 if I use a normal micro USB cable (not USB 3.0 one) I can mount my disk (with uas module) BUT it not works properly.

USB-UART device from Exar Co. not working with cdc_acm but usbserial
Hi, I've been trying to get this device work in linux Mint Qiana (3.13.0-24-generic) without success. The XR21V1414 is a multiport USB-UART device. (0x04e2:0x1414) (The driver provided "Vizzini" causes system crash due a improper initialization of tty_port) http://www.exar.com/common/content/default.aspx?id=10296 The cdc_acm driver creates the proper ttyACMx but there's no communication with the device. The only way I could get functional devices was with # rmmod cdc_acm # modprobe usbserial vendor=0x04e2 product=0x1414 And there's where I got the message from dmesg that I should contact to get a proper driver for my device. Thank you for your hard work, I hope this help to more people like me in the future. This is the output from lsusb, tell me if you need more information Bus 001 Device 015: ID 04e2:1414 Exar Corp.
