Ok, I just tried that. Did not work. USB.pm did not get installed, and when I run "cpan Device::USB", I get a ton of error messages - here are the first few lines: `USB.xs:6:17: error: usb.h: No such file or directory USB.xs: In function 'libusb_get_busses': USB.xs:32: warning: return makes pointer from integer without a cast USB.xs: In function 'libusb_open': USB.xs:37: warning: return makes pointer from integer without a cast USB.xs: In function 'libusb_close': USB.xs:42: error: 'usb_dev_handle' undeclared (first use in this funct +ion)` [download] It seems the reason for the error needs to be addressed instead of suppressed. What could be causing the failure to install? How to make it install w/o using force?	[reply] [d/l]

Ok, I just tried that. Did not work. Sure it did :) it installed the Inline module whose test was failing USB.xs:6:17: error: usb.h: No such file or directory Yeah, you can't force your way past modules that can't build because you're missing (non-perl) prerequisites http://search.cpan.org/dist/Device-USB/README says install libusb by any means , then you can install Device::USB Device::USB::FAQ says you can get it from http://libusb.sourceforge.net/ ( http://www.libusb.org/ ) So sudo apt-get install libusb-dev or some variation of such or .... before you can cpan Device::USB	[reply]
