Possible Mini USB Keyboard issue

Former Member
Former Member over 13 years ago

Hi,

 

I've taken delivery of a Raspberry Pi and have been through the boot sequence with it and can log on to it as root.

 

I was offered various options (I guess, by the Debian BIOS) when I initially started it up, one of which was to choose the type of keyboard that would be used with it.

 

I bought one of these specifically for that:

 

http://uk.farnell.com/jsp/search/productdetail.jsp?sku=1826378&CMP=i-bf9f-00001000

 

 

Part Num.           Qty. ordered Product description  Mnfr Part #

1826378  1 HK2007 KEYBOARD, MINI USB    HK2007

 

 

and I think, from memory, I chose 'A4TECH21' from the dropdown list of available keyboard types in the startup sequence.

 

When I log in and try to type at the command line the 'w', 's' and 'x' characters don't work. I don't know if it's the device itself is the issue or my choice of keyboard in the startup.

 

I plugged it in to a laptop and the result was the same (the keys above still didn't work). Should I send the keyboard back, or can I choose the keyboard again as part of the startup sequence, if so, how can I do that?

 

Any help much appreciated,

 

Thanks in advance

Pat

    If the keys don't work when connected to the laptop, then the choice of keyboard layout within the OS on the Pi is not relevant. If I were you, I'd return it as faulty.

    Maybe the laptop was some kind of unusual device too, such as an ARM netbook?  If so, plug it in to a normal x86 PC of some kind first to check whether it works or not.

     

    Before buying USB devices for Pi or other ARM machines, always check that they're "USB class compliant" first, because otherwise they may require closed source drivers and that's generally not going to work on ARM.  Unfortunately the packaging doesn't always declare class compliance, so some googling may be required first.

     

    If it's just those 3 keys that don't work though, it really does seem that you have a faulty unit.

     

    PS. Full QA on bottom-end, human-actuated devices is somewhat problematic, because robotic test equipment to physically poke every key on every unit could blow the product out of its price niche.  That's likely to mean that QA is just human and performed on random samples ... and you know what that implies.

     

    Morgaine.

    Pat, I think it is a faulty keyboard.

    I use a cheapest of the cheap USB keyboard with my Pi and it is fine. If it exhibits the same behaviour on another machine then I think it is RMA time unfortunately.

    Thanks, Steve, RMA already in place and Farnell are replacing the device with no quastions asked, fair play to them.

    The Foundation chose well with Farnell and RS, both great companies.
