Bug#766570: USB keyboard unresponsive after kernel load, but mouse works (Jessie Beta 2 amd64)

["Daniel F. Smith" <Daniel@Smith.net>]

Thanks KiBi,

I tried the keyboard (and USB stick) in both the USB2 and USB3 ports. 
No difference.

I did find an old blog post[1] describing the issue, and it suggests 
adding the following to initrd.img (/etc/initramfs-tools/modules):
  usbcore
  uhci_hcd
  ehci_hcd
  ehci_pci
  usbhid
  hid_generic

I don't currently have a Jessie system to run update-initramfs, but I'll 
can copy an initrd onto the USB stick if someone can provide one.

(And you're probably right about syslinux---the BIOS found two 
bootloaders: a text one and a graphical one with swooshes; and I didn't 
look closely!)

Daniel
