This should do the trick with no struct changes:
#if defined(__GNUC__)
#define _BytePacked_ __attribute__ ((packed))
#define Packed_Struct struct _BytePacked_
#else
#define _BytePacked_
#define Packed_Struct struct
#endif
#pragma pack(push)
#pragma pack(1)
typedef Packed_Struct arawana_usb_cmd
{
unsigned char tmpbuf[8];
} tmpstruct;
#pragma pack(pop)
