(Originalle reported by Hitachi tester) Some keys can't be input by USB 106 keyboard on Console: can't input "|","\"and "_" on X window: can't input "_" and "\" Test machine: Hitachi FLORA 310LV LA1 Chiptset: i810E USB keyboard Here is the spec of the machince http://www.hitachi.co.jp/Prod/comp/OSD/pc/flora300/spec/310_la1.htm Now this bug has been fixed on Laser5 Linux 6.4. Since there is no ps2 port on this serial machine,only usb ports are used. The bug was occured in Fisher and Wolverine. There are some discussion on the url below.(Sorry,in Japanese) http://his.luky.org/ML/linux-users.7/msg04489.html Here are some possible reasons: 1)It is not enough to use scancode of ps/2 keyboard for usb keyboard,AT set 2 and AT set3 shall also be defined for USB keyboard. 2)The patch may fix the bug.the file is attached.

I do not understand if the Laser5 patch is safe. Davem says it may impair keyboards with additional keypad characters KeyPAD-comma or KeyPAD-RightPAREN. I sent a question to Vojtech, so far no reply.
Opening the bug to the public - if Lazer5 ships the fix, should be no problem. The 7.1 release passed too. Still talking to Vojtech about the fix, believe it or not :)
The plot thickens. Somebody filed a Bug 51142. However, they refer to TurboWS, which has a different change (not even overlappting with Lazer5). Lazer5 changes USB offsets 0x7c (backslash, underscore), 0xb4 (Yen, pipe). Turbo changes 5 symbols, at offsets from 0xb5 to 0xb9, with resulting codes for 5 additional keys. See http://euc.jp/i18n/jpkbd.en.html. Can anyone with access to the hardware define DEBUG in drivers/usb/hid.c and send me output for each particular key? (Do not define DEBUG_DATA).
I think Lazer5 is full of it - scancodes are not where they have to be. Look at #51142 for the reference and contact Nakai-san for userland questions.
