In usb.inc all required Linux include files of the Linux code are looked up by 'sed'ing through the files of SRC_C and SRC_CC. The Linux include files are then added as dependency to the SRC_C and SRC_CC files and during dependency resolution symbolic links to the lx_emul.h will be created. In the platform specific usb.mk file there are the Linux driver files added, but unfortunately after including usb.inc. So, for them no dependency to any Linux include header file is generated and so no symbolic files are generated. If the driver code file is compiled as first, as for asix.c, the symbolic links of the include files are missing and compilation fails. Add the Linux driver code files to SRC_C before including usb.inc in the platform specific usb.mk files. |

Device drivers ported from the Linux kernel USB ### HID ~~~ Supports keyboard and mouse. A run script can be found under 'run/usb_hid.run'. Configuration snippet: !<start name="usb_drv"> ! <resource name="RAM" quantum="3M"/> ! <provides><service name="Input"/></provides> ! <config> ! <hid/> ! </config> !</start> Note: It has been observed that certain 1.0 versions of Qemu do not generate mouse interrupts. The mouse driver should work correctly on Qemu 1.0.93 and above. Storage ~~~~~~~ Currently supports one USB storage device. Hot plugging has not been tested. A run script can be found under 'run/usb_storage.run'. Configuration snippet: !<start name="usb_drv"> ! <resource name="RAM" quantum="2M"/> ! <provides> <service name="Block"/> </provides> ! <config><storage /></config> !</start> Network (Nic) ~~~~~~~~~~~~~ Supported on PandaBoard only using the 'smsc95xx' driver. Configuration snippet: !<start name="usb_drv"> ! <resource name="RAM" quantum="3M"/> ! <provides> ! <service name="Nic"/> ! <service name="Input"/> ! </provides> ! <config> ! <nic mac="2e:60:90:0c:4e:01" /> ! <hid/> ! </config> !</start> Please observe that this setup starts the HID and Nic service at the same time. Also there is the 'mac' attribute where one can specify the hardware address of the network interface. This is necessary in case the EEPROM of the network card cannot be accessed via the host controller making it impossible to retrieve the devices hardware address. If this is the case and no 'mac' attribute is given a fallback address will be assigned to the network device. Note that the fallback address will always be the same.
