Ram corruption

[fabiodl]

Here is the result of 3 days of head scratching (huge thanks for this project, btw!) ;)

USBHost.c has

__at(0x0000) unsigned char __xdata RxBuffer[MAX_PACKET_SIZE];
__at(0x0100) unsigned char __xdata TxBuffer[MAX_PACKET_SIZE];

but the SDCC manual (page 42) reports
The compilerdoesnotreserve any space for variables declared in this way (they are implemented with an equate in the assembler).
and indeed I had memory corruption.

__at(0x0000) unsigned char __xdata RxBuffer[MAX_PACKET_SIZE]={0};
__at(0x0100) unsigned char __xdata TxBuffer[MAX_PACKET_SIZE]={0};

fixes it
