Need help with gridseed in Linux

I just recieved the gridseed ASIC miner in the mail. I have successfully gotten it to mine litecoin in linux with cgminer. But unfortunately I haven't gotten it working with bitcoin. I am mining from slush pool and don't start telling me that it's not worth it. I didn't expect it to be, I'm just a hobbyist. I have the cgminer command written down. I have cgminer recognizing the gridseed device, I just cant get it to show that it has connected and start displaying the status of it's mining job. I can do it with ltcrabbit and hypernova but I am unable to mine bitcoin from slush pool. Here is the command I used
cgminer -o stratum+tcp://stratum.bitcoin.cz:3333 -u baronobeefdip.worker1 -p ****
Nothing is working, I want to know how I can make it communicate with the pool. I did download a special version of cgminer that was compatible with the gridseed device so I think it might need some updating. As for the device itself, the drivers for the console should be already in the kernel. I am thinking that there is more to be done here when it comes to bitcoin, I understand it's an entirely different animal and one cannot switch inbetween the two.

PSA : Expiry - Scan-time - Queue

Link : https://bitcointalk.org/index.php?topic=448649.msg5494025#msg5494025
Also there's a lot of poor and misguided advice on how the expiry, scan-time and queue settings actually influence the rejections you're experiencing. A lot of these settings were made for HTTP communication and not the much more efficient stratum protocol*.
--expiry This setting defines how long time it takes before a work share is declared stale. It is [u]not used[/u] on stratum servers, since stratum servers supply it with work shares. Only exception is when the statrum server is broken, then the setting is used as a fallback value.
Recommendation: Leave at default setting. Server will supply a proper setting.
To verify above simply follow the opt_expiry variable in cgminer.c source file.
--scan-time This setting defines how long time, in seconds, the client should spend scanning current active work. Again a setting that is [u]not used[/u] on stratum servers, since stratum servers supply it with work shares. Only exception is when the setting is lower than the server supplied setting, then it'll potentially generate more stale work.
Recommendation: Leave at default setting, which is 30 seconds for scrypt.
To verify above simply follow the opt_scantime variable in cgminer.c source file.
--queue This setting defines how many work items you minimum got waiting in queue. It is only relevant to prevent downtime when the stratum server is too slow at serving new work shares.
Recommendation: Leave at default setting, which is 1.
To verify above simply follow the opt_queue variable in cgminer.c source file.

New R-Box Help

Hello.
I have been successfully running my New R-Box on my Windows PC for some time but want to run it off a raspberry pi now to save on power.
When I open up the cgminer, this is what i'm presented with:

cgminer version 4.9.1 - Started: [2015-06-18 00:04:38]

I don't really know what much of this means or how to fix it. I don't have a driver installed on the r-box at the moment. I really just need to get cgminer to see my miner and talk with it. I have cgminer set up correctly.
Ask any questions if I'm not giving enough info. Thanks!

[HELP] Cgminer can't access Antminer U2.

I've followed the instructions for installing the Silicon Labs driver and replacing it wit Zadig, however I can't seem to get cgminer to recognize it.
Here is a screenshot of the current zadig config: http://i.imgur.com/xitOXQz.png
I am using this in the command-line:
cgminer.exe --anu-freq 200 -o stratum+tcp://stratum.bitcoin.cz:3333 -u zacker150.worker1 -p anything 
And this is what cgminer outputs: http://i.imgur.com/6eGeSpj.png
After going to USB Management >> List All Known Devices, this is what is outputted: http://i.imgur.com/vVMd3dK.png
This happens regardless of whether I run cgminer as an administrator.

building a miner

I am trying to write a litecoin miner as a practice project but am unclear on some of the process. Following the stratum-mining description(http://mining.bitcoin.cz/stratum-mining#stratum) I was able to build the block header. using wireshark and cgminer debugging I confirmed my initial block header matches the cgminer block header. I am not sure what the next step should be though.
I have generated the coinbase transaction using the Extranonce1 + Extranonce2(padded). After creating the merkle root and joining all the fields I then run it through a double sha and run the output of that through scrypt right?
If that is the case, Is the next step to increment the Extranonce2, regenerate the coinbase/merkle, and run it through scrypt again?
Please let me know if there is a better place to ask these kind of questions.

GUIminer returning "Verification failed, check hardware" on HD 6870. BitMinters Client is working though.

I want to use GUIminer and more specifiaclly I want to use the poclbm kernel because it allows me to set the -f 60 flag, which allows me to play games (league of legends) while mining. However GUIminer returns:

(0:0:Barts, a4bfd3a7) 2013-11-20 14:15:19: Listener for "GPU #1" shutting down 
I googled for a solution which said I should downgrade to CCC version 11.11, however this is not ideal since it would negatively affect my gaming experience. I also heard that BitMinter had a very easy to use client, so I decided to give that a shot. This client is indeed easy, as it immediatly worked! My work got accepted for the most part (5 stale out of 300+ proofs of work), however this is not the pool I want to mine in and the client does not allow me to set any parameters.
Anyone know a solution, obviously there are miners that could work with my card (BitMinter), but I did not find them yet. I tried GUIminer, Phoenix and CGminer.
PS: Please don't comment on whether mining is viable for me. I want to participate in Bitcoin mining with my gaming PC, my question is not about viability.
