USB Mass Storage Class

いきなり細かいところからですいません。本来はパケットだの、フレームだのSETUPがどうのと、始めるのでしょうが・・・
データトレースを見てデバッグ中の参照頻度の多い順です。エンディアンが（どっちか忘れましたが）通常と逆なので注意が必要です

　

CBW　Command Block Wrapper

フィールド	説　明
dCBWSignature	CBWのEyeキャッチ ASCIIコードで"USBC"、　なかなかお茶目ですよね
dCBWSignature	CBWのEyeキャッチ ASCIIコードで"USBC"、　なかなかお茶目ですよね
dCBWTag	コマンドブロックタグ。CBWとCSWを関連付けるための任意の値らしい並行動作出来るってことですよね
dCBWTag	コマンドブロックタグ。CBWとCSWを関連付けるための任意の値らしい並行動作出来るってことですよね
dCBWDataTransferLength	データトランスポートの推定データ長（バイト数）。ここが0 の場合データトランスポートは存在しません
bmCBWFlags	ビット7 が0 の場合、データトランスポートはバルクアウト転送で行われ、　　　 1 の場合、バルクイン転送で行われます。ビット6～0 は0 固定
bCBWLUN	論理ユニット番号（Logical Unit Number）
bCBWLUN	論理ユニット番号（Logical Unit Number）
bCBWCBLength	次のCBWCB フィールドの有効バイト数
bCBWCBLength	次のCBWCB フィールドの有効バイト数
CBWCB	実行されるコマンドブロック(Read、Writeなど)を格納するフィールド SCSIコマンドに準拠しているみたい

　
ふぅーっ。。。
CBWだけで疲れました。表組みではなくExcellで説明作れば楽なのですが、見栄えが・・
本当はUSBの仕様書を見るべきなのでしょうが、ポチは日本語しか分かりません。ターゲットとして書かれていますが、この辺のルネサスのドキュメントは役に立ちます。ポチへの影響大きく（他に適当なドキュメントが見当たらないので）、UFIだと思い込んでいる大きな要因です
　
　

CSW Command Status Wrapper

フィールド	説　明
dCSWSignature	CSWのEyeキャッチ ASCIIコードで"USBS"
dCSWTag	CBWとCSWを結びつけるためのID。関連するCBWのdCBWTagが返却されると想定されるが、今の処使っていない（とりあえず今は０固定）
dCSWDataResidue	CBW のdCBWDataTransferLength 値と実際にファンクションが処理したデータ量の相違を報告します
bCSWStatus	コマンドの実行結果。コマンドが正常に完了した場合、ターゲットは0x00を返却します。ゼロ以外の値は次の通りとし、コマンド実行時の不具合を示しますコマンドフェイルは0x01、フェーズエラーは0x02。

シーケンス

パクリました（オリジナルは仕様書にあったような）。パクっておいて言うことではないですが、絵にする程では無いですよね・・。
要はCBWとCSWでバルク転送をサンドウィッチってことですね
CBWの後半には下記のSCSIコマンドが続いており、それでBulk INかBulk OUTが決まる。送信方向は

CBW : HOST →　Target
CSW : Target →　HOST

ここまで簡単そうなのですが、CSWが却って来なかったりで結構苦労します
　
　

Universal Serial Bus Mass Storage Specification For Bootability

信用しないでください。そもそも見ているドキュメントを間違っているような・・・。Bootabilityが怪しいです。WRITE(10)もない
　
3.1 INQUIRY Command
　
3.2 READ(10) Command
　
3.3 REQUEST SENSE Command
　
　　　　　Additional Sense Code
　　
3.4 TEST UNIT READY Command
　
4.1 MODE SENSE(10) Command
　
4.2 READ CAPACITY

　

3　Device Required Command Support

3.1 INQUIRY Command

　
（１）CBW+INQUIRYコマンド形式

　
（２）INQUIRY Data形式（BULK INで受信、その後、CSWを受信）　

　
Vendor Identification、Product Identification、Product Revision LevelはASCIIコードです
アクセス上の重要な情報は含まれません
トレース上はCBWとSCSIコマンドは連続しているのですが、既存ドキュメントはなぜか別々で説明されています。トレースが読み辛いので一緒にしました

　
　

3.2 READ(10) Command

　
（１）CBW+READコマンド形式

フィールド	説　明
Logical Block Address	The logical block at which the read operation begins. と、言っても何のことか？？、セクタの通し番号です
Logical Block Address
Transfer Length	The number of contiguous logical blocks of data that are transferred. 転送セクタ数です。通常、（Transfer Length）×512Bytesが転送されます尚、dCBWDataTransferLengthにはバイト数を指定します
Transfer Length

　
上記は両方ともエンディアンには注意が必要です
　

No	転送	データ
1	BULK OUT	CBW+READコマンド
2	BULK IN	（実際の）READデータ
3	BULK IN	CSW

と、いう感じです。簡単ですよね、動けば・・。
しかし、SCSI準拠か何か知りませんがワード境界を無視したり、予備領域が多かったり、よく分かりません

なお、READにはREAD(10)以外にも沢山の種類があります。DISK容量の増加に対応したのだと思います
　
　　

3.3 REQUEST SENSE Command

Additional Sense Code

　
　英語が分からないので、よく分かりませんが、権威のありそうなページです
　SCSI Common Codes & Values
　
　手近かにはここでも
　Key Code Qualifier Wikipedia
　
センスの意味が分かれば、バグの原因が分かる訳ではないですが、分からないと気になります

3.4 TEST UNIT READY Command

　
Operation Codeしかない単純なコマンドですが、ハマりました。「アキバオー」で買ったUSBメモリは電源ON直後だけ、TEST UNIT READYに対してCSWでエラーを返します。REQUEST SENSEでSENSEを調べると28hで"Not Ready to Ready"（文字通りの解釈で良いのか？）でした。単純にTEST UNIT READYを繰り返しましたが何度送っても、CSWはエラーのままです。（SH-2AをRESETして(電源OFFしないで)実行し直すと、正常に立ち上がります）
　
途方に暮れていたのですが、ATTACHEDから処理をし直すと立ち上がりました
フ－ッ！
　
本来のリトライの仕方は分かりません
　
　

4 Read/Write Media Device Required Commands　　

4.1 MODE SENSE(10) Command

（ポチは）使ってません
　
　

4.2 READ CAPACITY

　
ディレクトリの更新（ファイルの追加など）にはDISK容量が必要なようです
この章にあるということは、READ-ONLYでアクセスする場合は不要です

5 CD/DVD Device Required Commands

　
すいません。CDのアクセスやブート動作には興味がないので、省略します。原本を参照ください
