Hi all,
I have a Cisco WUSB600N V2 with Ralink 3572 as the chipset
I have downloaded the driver (2011_0427_RT3572_Linux_STA_v2.5.0.0) from ralink official site
and I need for my project to find the place in the driver code where the retry limit is increased after a data packet drop
and I've found this:

do
{
if (RTMP_TEST_FLAG(pAd, fRTMP_ADAPTER_NIC_NOT_EXIST))
return;
/* Write 0x90 to BBP_R25 to transmit test tone*/
RTMP_BBP_IO_WRITE8_BY_REG_ID(pAd, BBP_R25, 0x90);

RTMPusecDelay(1000);
/* Read BBP_R55[6:0] for received power, set R55x = BBP_R55[6:0]*/
RTMP_BBP_IO_READ8_BY_REG_ID(pAd, BBP_R55, &value);
R55x = value & 0xFF;

} while ((ReTry++ < 100) && (R55x == 0));

in the file rt30xx.c in the directory chips but I am not sure if this is really what I want so can anyone confirm it to me?

please help I am very new to drivers
Thanks in advance
