Browsing the source with a cross referencing tool (http://lxr.free-electrons.com) and making additional checking points, I could trace the issue as follow. The problem is that this device returns a regulatory region of 0x49, which is not defined in the zd1211rw tables. So the call r = zd_reg2alpha2 (mac ->regdomain, alpha2); will fail the initialization process. Workaround: ----snip---- int zd_mac_init_hw(struct ieee80211_hw *hw) { ... r = zd_read_regdomain(chip, &default_regdomain); /* A unknown regulatory of 0x49 will be set default to ZD_REGDOMAIN_FCC. */ if (0x49 == default_regdomain) default_regdomain = ZD_REGDOMAIN_FCC; ... ----snip---- The above code will force the default regulatry to be FCC code for this case. I think that this was the case in previous zd1211rw driver. What is the country code for 0x49 region? There is a better way? Thanks all, Phew!! Leonardo
