25 o. Copy the firmware image (e.g. usb8388.bin) to /lib/firmware/
27 o. Load driver by using the following command:
29 insmod usb8388.ko [fw_name=usb8388.bin]
31 =========================

36 Use the -i option to retrieve version information from the driver.
40 version: COMM-USB8388-318.p4
41 firmware-version: 5.110.7
44 Use the -e option to read the EEPROM contents of the card.
47 ethtool -e ethX [raw on|off] [offset N] [length N]
49 -e retrieves and prints an EEPROM dump for the specified ethernet
50 device. When raw is enabled, then it dumps the raw EEPROM data
51 to stdout. The length and offset parameters allow dumping cer-
52 tain portions of the EEPROM. Default is to dump the entire EEP-

64 those commands are used via debugfs interface
70 These commands are used to read the MAC, BBP and RF registers from the
71 card. These commands take one parameter that specifies the offset
72 location that is to be read. This parameter must be specified in
73 hexadecimal (its possible to preceed preceding the number with a "0x").
75 Path: /sys/kernel/debug/libertas_wireless/ethX/registers/
78 echo "0xa123" > rdmac ; cat rdmac
79 echo "0xa123" > rdbbp ; cat rdbbp
80 echo "0xa123" > rdrf ; cat rdrf
84 These commands are used to write the MAC, BBP and RF registers in the
85 card. These commands take two parameters that specify the offset
86 location and the value that is to be written. This parameters must
87 be specified in hexadecimal (its possible to preceed the number
91 echo "0xa123 0xaa" > wrmac
92 echo "0xa123 0xaa" > wrbbp
93 echo "0xa123 0xaa" > wrrf
96 This command is used to set the sleepclock configurations
98 Path: /sys/kernel/debug/libertas_wireless/ethX/
101 cat sleepparams: reads the current sleepclock configuration
103 echo "p1 p2 p3 p4 p5 p6" > sleepparams: writes the sleepclock configuration.
106 p1 is Sleep clock error in ppm (0-65535)
107 p2 is Wakeup offset in usec (0-65535)
108 p3 is Clock stabilization time in usec (0-65535)
109 p4 is Control periodic calibration (0-2)
110 p5 is Control the use of external sleep clock (0-2)
111 p6 is reserved for debug (0-65535)
115 The subscribed_events directory contains the interface for the
116 subscribed events API.
118 Path: /sys/kernel/debug/libertas_wireless/ethX/subscribed_events/
120 Each event is represented by a filename. Each filename consists of the
121 following three fields:
122 Value Frequency Subscribed
124 To read the current values for a given event, do:
126 To set the current values, do:
127 echo "60 2 1" > event
129 Frequency field specifies the reporting frequency for this event.
130 If it is set to 0, then the event is reported only once, and then
131 automatically unsubscribed. If it is set to 1, then the event is
132 reported every time it occurs. If it is set to N, then the event is
133 reported every Nth time it occurs.
136 Value field specifies the number of consecutive missing beacons which
137 triggers the LINK_LOSS event. This event is generated only once after
138 which the firmware resets its state. At initialization, the LINK_LOSS
139 event is subscribed by default. The default value of MissedBeacons is
143 Value field specifies the consecutive failure count threshold which
144 triggers the generation of the MAX_FAIL event. Once this event is
145 generated, the consecutive failure count is reset to 0.
146 At initialization, the MAX_FAIL event is NOT subscribed by
150 This event is generated when the average received RSSI in beacons goes
151 above a threshold, specified by Value.
154 This event is generated when the average received RSSI in beacons goes
155 below a threshold, specified by Value.
158 This event is generated when the average received SNR in beacons goes
159 above a threshold, specified by Value.
162 This event is generated when the average received SNR in beacons goes
163 below a threshold, specified by Value.
166 This command is used to do a specific scan.

170 Usage: echo "SSID" > extscan
173 echo "LINKSYS-AP" > extscan
175 To see the results of use getscantable command.
179 Display the current contents of the driver scan table (ie. get the
182 Path: /sys/kernel/debug/libertas_wireless/ethX/
188 Initiate a customized scan and retrieve the results
191 Path: /sys/kernel/debug/libertas_wireless/ethX/
194 echo "[ARGS]" > setuserscan
198 bssid=xx:xx:xx:xx:xx:xx specify a BSSID filter for the scan
199 ssid="[SSID]" specify a SSID filter for the scan
200 keep=[0 or 1] keep the previous scan results (1), discard (0)
201 dur=[scan time] time to scan for each channel in milliseconds
202 type=[1,2,3] BSS type: 1 (Infra), 2(Adhoc), 3(Any)
204 Any combination of the above arguments can be supplied on the command
205 line. If dur tokens are absent, the driver default setting will be used.
206 The bssid and ssid fields, if blank, will produce an unfiltered scan.
207 The type field will default to 3 (Any) and the keep field will default
211 1) Perform a passive scan on all channels for 20 ms per channel:
212 echo "dur=20" > setuserscan
214 2) Perform an active scan for a specific SSID:
215 echo "ssid="TestAP"" > setuserscan
217 3) Scan all available channels (B/G, A bands) for a specific BSSID, keep
218 the current scan table intact, update existing or append new scan data:
219 echo "bssid=00:50:43:20:12:82 keep=1" > setuserscan
221 4) Scan for all infrastructure networks.
222 Keep the previous scan table intact. Update any duplicate BSSID/SSID
223 matches with the new scan data:
224 echo "type=1 keep=1" > setuserscan
226 All entries in the scan table (not just the new scan data when keep=1)
227 will be displayed upon completion by use of the getscantable ioctl.
