Youch.  I hate it when that heppens.  Hope it wasn't
because you got a power spike ;-)

Let me or Georg know if you want us to run any debug
code.  Feels like a bcmxcp_usb driver bug to me since
the bcmcxp serial driver works fine and all my other
USB devices work fine (wifi adapter, memory card
reader, etc.)

Hi,

The problem was reported to me by Charlie Garrison
that helped me testing the 5115 usb.

The first implementation was not done by powerware.
So if you look at the code in drivers/nut_usb.c
line 58.
--------------------------------------------------
/* XXX Check for POWERWARE 3105 or 3110 ... other models??? */
	if (dev->descriptor.bDeviceClass == USB_CLASS_PER_INTERFACE &&
	    (dev->descriptor.idVendor == 0x0592 ||
	     dev->descriptor.idVendor == 0x06da) &&
	    dev->descriptor.idProduct == 0x0002 &&
	    dev->descriptor.iManufacturer == 1 &&
	    dev->descriptor.iProduct == 2)
		return usb_open(dev);
-----------------------------------------------------

It check the iManufacturer and iProduct code. 
This is not the same on the 5115 and 3110.
So that is why it can't open the device.

It should look like this.
----------------------------
    dev->descriptor.iManufacturer == 4
    dev->descriptor.iProduct == 24
-------------------------------

Or you may remove the lines like this
----------------------------------------
/* XXX Check for POWERWARE 3105 or 3110 ... other models??? */
	if (dev->descriptor.bDeviceClass == USB_CLASS_PER_INTERFACE &&
	    (dev->descriptor.idVendor == 0x0592 ||
	     dev->descriptor.idVendor == 0x06da) &&
	    dev->descriptor.idProduct == 0x0002)
		return usb_open(dev);
-----------------------------------------

Check this by
lsusb -v
And read the descriptor.
This is from a 3105:
-----------------------------------------
Bus 001 Device 002: ID 0592:0002 Powerware Corp.
Device Descriptor:
  bLength                18
  bDescriptorType         1
  bcdUSB               2.00
  bDeviceClass            0 (Defined at Interface level)
  bDeviceSubClass         0
  bDeviceProtocol         0
  bMaxPacketSize0         8
  idVendor           0x0592 Powerware Corp.
  idProduct          0x0002
  bcdDevice            0.80
  iManufacturer           1 Powerware
  iProduct                2 Powerware UPS
  iSerial                 0
  bNumConfigurations      1
-----------------------------------------

Now i'm back on my computer.
And it was no spike. Just and old board that have
been running for to long. Changed some capacitors
that have started to leak.

Regards
Kjell
