Hello,
I have ISP1760 on Blackfin DSP board with the following board specific configuration (linux 2.6.28):
static struct isp1760_platform_data isp1760_priv = {
.is_isp1761 = 0,
.port1_disable = 0,
.bus_width_16 = 1,
.port1_otg = 0,
.analog_oc = 0,
.dack_polarity_high = 0,
.dreq_polarity_high = 0,
};
USB Flash drive is working OK

However WiFi USB module (rtl8187) gives results similar to described in previous thread:

After a bunch of these messages, the board reboots by watchdog

Previous unofficial pehci driver was working ok with WiFi:

Any suggestions to track down the problem?
